Abstract:

Chiral N-sulfonyl-oxaziridines derived from 8-camphorsulfonic acid and fenchone have been evaluated as asymmetric oxidizing agents for the conversion of sulfides to chiral sulfoxides. There is no correlation between the redox potentials nor the 17O NMR chemical shifts of the oxaziridines and their relative oxidation rates, nor with the enantiomeric excesses achieved, indicating that steric effects are responsible for their behaviour. The results are consistent with an attack of one sulfur lone pair at the oxaziridine oxygen in such a way that both sulfur lone pairs lie in the plane of the oxaziridine ring. The most efficient oxaziridines, the camphorlactone-sulfonyloxaziridine [(4aS,9 aR)-10,10-dimethyl-6,7-dihydro-4 H-4 a,7-methano-oxazirino[3,2-j]oxepino[3,4-c]isothiazol-9(5H)-one 3,3-dioxide] and the 3-endo-bromocamphorsulfonyloxaziridine [(4aS,8 S,8 aR)-8-bromo-9,9-dimethyl-5,6,7,8-tetrahydro-4 H- 4a,7-methano-oxazirino-2,1-benzisothiazole 3,3-dioxide] allow the preparation of chiral sulfoxides with up to 85% enantiomeric excess.

Abstract:

(1 S) - (+)-Fenchone is sulfonated by SO3 or H2SO4/acetic anhydride in the bridgehead methyl group. This could be confirmed by NMR techniques (INADEQUATE). The fenchonesulfonic acid obtained is converted (SOCl2/NH3) to the cyclic fenchonesulfonimide, which can be oxidized to the corresponding oxaziridine, in close analogy to 10-camphorsulfonimide. Improved procedures for this reaction sequences are given. During the treatment of the sulfonic acid with thionyl chloride, a byproduct with a rearranged bicyclic skeleton is observed whose structure has been determined by ozonolytic degradation and NMR techniques. A possible mechanism for this rearrangement is suggested, based on MNDO calculations of the intermediate carbocations. The fenchonesulfonyloxaziridine oxidizes sulfides to chiral sulfoxides with appreciable enantiomeric excess, but very low reaction rate. A comparison with camphor-derived oxaziridines having similar steric requirements is made.

Abstract:

The field of chemical modification of proteins has been dominated by random modification of lysines or more site-specific labeling of cysteines, each with attendant challenges. Recently, we have developed oxaziridine chemistry for highly selective modification of methionine called redox-activated chemical tagging (ReACT) but have not broadly tested the molecular parameters for efficient and stable protein modification. Here we systematically scanned methionines throughout one of the most popular antibody scaffolds, trastuzumab, used for antibody engineering and drug conjugation. We tested the expression, reactivities, and stabilities of 123 single engineered methionines distributed over the surface of the antibody when reacted with oxaziridine. We found uniformly high expression for these mutants and excellent reaction efficiencies with a panel of oxaziridines. Remarkably, the stability to hydrolysis of the sulfimide varied more than 10-fold depending on temperature and the site of the engineered methionine. Interestingly, the most stable and reactive sites were those that were partially buried, presumably because of their reduced access to water. There was also a 10-fold variation in stability depending on the nature of the oxaziridine, which was determined to be inversely correlated with the electrophilic nature of the sulfimide. Importantly, the stabilities of the best analogs were sufficient to support their use as antibody drug conjugates and potent in a breast cancer mouse xenograft model over a month. These studies provide key parameters for broad application of ReACT for efficient, stable, and site-specific antibody and protein bioconjugation to native or engineered methionines.

Abstract:

Oxidation of (3-oxo-camphorsulfonyl)imine (1) by magnesium monoperoxyphthalate does not lead to the oxaziridine obtained with 3-chloro-perbenzoic acid, but to a new chiral oxaziridine containing an additional oxygen atom (Baeyer-Villiger type oxidation). The structure of the product is established by X-ray crystallography, and reaction pathways for the oxidation of 1 by peracids are discussed.

Abstract:

AbstractFor the enantioselective oxidation of methyl phenyl sulfide and tert-butyl methyl sulfide to the corresponding chiral sulfoxides by 3,3-dibromo-(camphorsulfonyl)oxaziridine, semiempirical calculations (MNDO, AMI, PM3) concerning transition state geometries were performed. The results show that only PM3 is able to localize a transition state. For methyl phenyl sulfide, a spiro arrangement of the oxaziridine ring and the sulfur atom explains the observed direction of the selectivity better than a planar transition state. The solvent dependence of the observed enantioselectivity is related to the calculated dipole moment of the transition state by the Kirkwood-Onsager model. In THF as solvent, its direct participation in the transition state has to be considered

Abstract:

Species with three-membered rings and the amide linkage are well studied. A quick perusal of the literature with SciFinder finds some 50 000 references to cyclopropanes and almost 300 000 references to amides. In the current paper, we discuss the structure and energetics of two understudied three-membered ring amides, 1,2-oxaziridine-3-one (5) (simultaneously describable as the simplest cyclic carbamate and simplest hydroxamate) and aziridine-2,3-dione (7) (simultaneously describable as the simplest imide and simplest α-ketoamide), with but 5 and nearly 10 references, respectively, for these two classes of compounds. Neither 1,2-oxaziridine-3-one (5) nor aziridine-2,3-dione (7), nor any derivative thereof, has been isolated. Calculational theory ameliorates the paucity of experimental information. The current study reports our computational findings for these and related species (e.g., enols and imidols) where we have used the G3(MP2)//B3LYP method.

Abstract:

A tricyclic chiral auxiliary, prepared from the enzymatically derived cis-arene dihydrodiol metabolite of toluene, was investigated as a means of asymmetric induction in several different reactions. The auxiliary was converted to an oxaziridine, and its utility in hydroxylation, providing low levels of enantiomeric excess, was compared with that of Davis’s oxaziridine. Insight into the origin of stereoinduction in this reaction is provided and is based on computational Monte Carlo Multiple Minimum (MCMM) searches using the OPLS3 force field. The use of the auxiliary group in the alkylation of appended esters proved disappointing. Diels-Alder cycloaddition of an acrylate, derived from the auxiliary group, with cyclohexadiene furnished a mixture of diastereomeric adducts in essentially equal amounts. The adducts were separated and the corresponding enantiomeric residues were isolated with good enantiomeric excess. Evidence of reasonable levels of asymmetric induction in the above processes was lacking. Experimental and spectral data are provided for all key compounds.

Abstract:

A method for the synthesis of the head group of phospholipids is described. It is formed by ring opening of oxazaphospholanes, either by mild tetrazole mediated hydrolysis of λ3-oxazaphospholanes or by methylating ring cleavage of λ5-oxazaphospholanes. Oxidation can be performed by means of an oxaziridine.

Abstract:

The transannular electronic interactions in [2.2]paracyclophanes affect the selectivity of the tricyanovinylation reaction with tetracyanoethylene (TCNE). In addition to the normal N-tricyanovinyl product, 4-amino[2,2]paracyclophane reacts with TCNE to give oxaziridine derivatives. In the case of reaction with 4-N-methylamino[2.2]paracyclophane, the unusual N-tricyanovinylated product as well as 4-(N-carbonitrile-N-methyl)annino[2.2]paracyclophane was isolated. The reaction of 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) with 4-amino[2.2]paracyclophane results in formation of 2-cyano-3-(4-[2.2]paracyclophanyl)amino-5,6-dichloro-1,4-benzoquinone.

Abstract:

The geometry about oxygen in the transition-state structures for oxygen transfers from a nitrone to phosphorous, from a percarboxylic acid to a carboncarbon double bond, and from an N-sulfonyl oxaziridine to a carboncarbon double bond have been evaluated by the endocyclic restriction test. The former can proceed at an oblique angle, while the latter two require a large angle between the entering and leaving groups on oxygen. This information is used to determine the mechanism of the aldehyde-dependent oxygen transfer from molecular oxygen to a carboncarbon double bond.

Abstract:

Predictably site-selective catalytic methods for intermolecular C(sp3)–H hydroxylation and amination hold great promise for the synthesis and late-stage modification of complex molecules. Transition-metal catalysis has been the most common approach for early investigations of this type of reaction. In comparison, there are far fewer reports of organocatalytic methods for direct oxygen or nitrogen insertion into C–H bonds. Herein, we provide an overview of early efforts in this area, with particular emphasis on our own recent development of an iminium salt that catalyzes both oxygen and nitrogen insertion.1 Introduction2 Background: C–H Oxidation Capabilities of Heterocyclic Oxidants3 Oxaziridine-Mediated Catalytic Hydroxylation4 Dioxirane-Mediated Catalytic Hydroxylation5 Iminium Salt Catalysis of Hydroxylation and Amination6 Conclusion and Outlook

Abstract:

4,6-Dimethoxy-1,3,5-triazine-2-sulfenic acid (1) was prepared by the reaction of 4,6-dimethoxy-1,3,5-triazine-2(1H)-thion (3) with 2-benzenesulfonyl-3-(p-nitrophenyl)-oxaziridine (2) in THF solution and isolated as a stable crystalline solid. The new compound was characterized by analytical and spectroscopic data (IR, 1H and 13C NMR, UV, MS) supported by MNDO-PM 3 calculations. UV spectrometry was used for exact determination of the ionization constant of 1(pKa = 5.86 ± 0.02 at 20°C). According to 13C NMR data and X-ray analysis the sulfenic acid 1 adopts the sulfenyl structure (R—SOH) in the condensed phase.Crystal data of 1 (90 K): a = 8.418(3), b = 21.289(6), c = 4.411(1) Å, Z = 4, P 21212, R = 0.0304, Rw = 0.0354 for 4105 unique reflections and 122 parameters. In the crystal, the molecules form dimers by two strong intermolecular O—H ••• N hydrogen bonds. The 6-membered ring shows alternating C—N bond lengths and is almost planar. The experimental electron deformation density (EDD) decreases in the order C—N > C—O ≈ C—S > S—O and is described in detail for the vicinity of the S atom.
