Methanopyrrolidine-5-carboxylic acids (MetPyr-5-acids), or 5-syn-carboxy-2- azabicyclo[2.1.1]hexanes are building blocks for β-peptides that cannot form backbone hydrogen bonds. To introduce functionality to this ring system, 6-syn-benzyloxymethyl and 6-syn-phenyl substituted derivatives have been prepared by an efficient synthetic procedure. Addition of appropriately substituted allyl amines to 3-butynone, amide protection, and irradiation afford mainly 5-acetyl-2-azabicyclo[2.1.1]hexanes. Haloform oxidation leads to the desired 6-substituted MetPyr-5-acids. A 1-ethoxycarbonyl-MetPyr-5-acid also was prepared in high yield. Condensation of ally amine with ethyl 2,4-dioxopentanoate afforded ethyl 2-(allylamino)-4-oxopent-2- enoate, and this was protected to give ethyl 2-[allyl(tert-butoxycarbonyl)amino]-4- oxopent-2-enoate. Irradiation afforded 5-syn-acetyl-1-ethoxycarbonyl-2- azabicyclo[2.1.1]hexane with high stereoselectivity and oxidation of the acetyl group afforded the desired 1-ethoxycarbonyl-MetPyr-5-acid. Resolutions of (±)-6-syn-benzyloxymethyl-MetPyr-5-acid and (±)-1- ethoxycarbonyl-MetPyr-5-acid were carried out (> 98% ee) by a classical resolution method using (S)-(-)-α-methylbenzylamine. The absolute configurations of (1S,4R,5R,6S)-(-)-6-benzyloxymethyl-MetPyr-5-acid and (1R,4S,5S)-(+)- 1- ethoxycarbonyl-MetPyr-5-acid were determined by X-ray analysis of their 5-(S)-(-)-α- methylbenzylamide. A prior X-ray analysis of N-Boc-(MetPyr)4-CO2Me indicated all amides to be trans oriented with all 5-syn-carbonyl groups directed toward Carbon-4 of the methanopyrrolidine. These structures were assigned as T4T4T4T4 or [T4]n (n = 4). The solution structure was not determined. Homooligomers of (1S,4R,5R)-5-syn-carboxy-2- azabicyclo[2.1.1]hexane (MPCA) terminally protected as N-Boc methylesters were constructed by EDC/HOBt coupling of terminal ester N-deprotected free amine units and N-Boc free acid units. To facilitate NMR analysis of the secondary structures of homooligomers, N-Boc was replaced by N-isobutyryl. NMR experiments indicated that N-isobutyryl-(MetPyr)n-CO2Me, (n = 2, 3, 4) have major favored [T4]n-1T where the orientation of the terminal ester carbonyl could not be determined.

Two research projects are described: studies of the synthesis of alpha-amino-alpha-alkylsilanes, the synthetic precursor of silanediol-based protease inhibitors, and the synthesis and stability evaluation of silanediol amino acids with an unprecedently unhindered silanediol group. Two methods were investigated as approaches to alpha-amino-alpha-alkylsilanes. First, a silicon-substituted aziridine was chosen as the precursor of an alpha-amino-alpha-alkylsilane via ring opening reactions with carbon nucleophiles. Silyl-substituted aziridines 2-24 and 2-30 were prepared via direct lithiation/silylation of aziridine and employed as substrates for ring opening reactions. In spite of many attempts to ring open these silylaziridines and prepare ?-amino-?-alkylsilanes, optimization of the reaction conditions were unsuccessful. Secondly, alpha-chloro-alpha-benzylsilane 3-12 was prepared as the precursor of an alpha-amino-alpha-alkylsilane via lithiation/benzylation. The alkylation at carbon alpha to silicon to give chloromethylsilane 3-14 was successful when using n-butyllithium for lithiation, which could be explained by the steric encumbrance inherent in the structure. Several attempts for nucleophilic displacement of chloride to obtain alpha-chloro-alpha-benzylsilane 3-11 were unsuccessful possibly due to the steric effect as well as the electronic effect of silicon on the alpha carbon which made the chloride less reactive toward nucleophilic substitution. The silanediol amino acid 4-1 was synthesized originally as a potential arginase inhibitor. Although the expected biological activity was not observed, the studies on silanediol-siloxane distribution of the silanediol amino acid revealed the unique properties of this compound. Under basic conditions, the silanediol amino acid was mainly stable in monomeric form. As the pH decreased, the silanediol amino acid gave a mixture of siloxanes which consisted of a variety of stereoisomers. With available instrumental techniques, monomer, dimers and trimers of the silanediol amino acid were identified.
