Abstract:
γ-Monosubstituted and trans-α,β-disubstituted γ-lactams were diastereoselectively synthesized from common intermediates (S)-N,N-dibenzylated aldehydes derived from natural l-(α)-amino acids, employing a divergent approach. The key features of the routes include diastereoselective Henry and Michael reactions that produced chiral γ-nitroester derivatives, which were subsequently submitted to a tandem reduction-lactamization sequence providing the title compounds. The versatility of routes can allow the preparation of several other mono-, di-, or tri-substituted γ-lactams.

Abstract:
Reductive deiodination of 2-deoxy-2-iodo-glycoside is an efficient and practical approach for the synthesis of 2-deoxyglycosides, which are moieties of bioactive compounds. However, inseparable diastereoisomers are usually formed in the preparation of 2-deoxy-2-iodo-glycosides via glycosylation of glycals with alcohols using current methods. To overcome this problem, a rapid and diastereoselective transformation of glycals and alcohols into 2-deoxy-2-iodo-α-glycosides enabled by I2/PhI(OAc)2 has been developed. 14 glycals, derived from 13 monosaccharides and one disaccharide, diastereoselectively yielded α-glycosides. Only in two cases the diastereoselectivity of the glycosylation was poor. The yields of glycosylation range from 73% to 95%, and the reactions are finished in only five minutes. Investigations for better diastereoselectivity by comparing I2/Ph(OAc)2- with I2/Cu(OAc)2-mediated glycosylations using UV analysis have been conducted.

PONSINET, RACHEL. "Synthese diastereoselective d'acides beta-amines." Paris 6, 1999. http://www.theses.fr/1999PA066411.

Full text
Abstract:
Si de nombreuses publications decrivent la synthese enantioselective d'acides -amines substitues en de la fonction acide (acides 3-amines) ou disubstitues en et , peu en revanche, concernent la synthese d'acides -amines uniquement substitues en (acides 2-amines). La plus grande partie du travail decrit dans cette these est axee sur une nouvelle voie de synthese diastereoselective d'acides 2-amines. Pour cela, deux strategies ont ete etudiees : la premiere correspond a une carboxylation enantioselective en d'une fonction nitrile (precurseur de la fonction amine). Elle est basee sur l'utilisation d'un electrophile chiral, obtenu par action du triphosgene sur le sultame d'oppolzer, et a conduit a la 2-phenylglycine enantiomeriquement pure. Mais elle n'est pas applicable a la synthese d'autres acides 2-amines a chaines laterales carbonees. La deuxieme strategie est basee sur l'alkylation d'un precurseur chiral derive de la -alanine. L'introduction de la chaine laterale de l'acide amine souhaite se fait avec une stereochimie induite par l'auxiliaire chiral : le sultame d'oppolzer. Cette strategie a permis d'obtenir la 2-phenylalanine, la 2-alanine et la 2-leucine avec d'excellents exces enantiomeriques. Elle necessite l'utilisation d'agents alkylants reactifs a basse temperature pour eviter l'elimination de l'enolate. Des etudes preliminaires portant sur l'introduction de chaines laterales fonctionnalisees (telles que celles de la lysine, de la methionine ou de l'acide aspartique) ont ete engagees, elles seront poursuivies. Les acides 2-amines aromatiques obtenus suivant ces deux strategies ont ete introduits dans la sequence de la substance p. Ces premiers analogues se sont averes etre peu affins et peu actifs. Une autre partie de ce travail a porte sur la mise au point d'une voie de synthese d'acides 3-amines (en particulier la 3-alanine) a partir de l'acide aspartique, en vue d'une application a grande echelle.

Abstract:
The diastereoselective synthesis of phosphite triesters and related phosphorothioate triesters and diesters has been investigated, with the goal of synthesizing diastereomerically pure DNA phosphorothioates.
Towards this end, the elaboration of a new heterobicyclic structure, imidazo-oxazaphosphorine such as 56, is reported. This unstable intermediate led to the highly diastereoselective synthesis of simple phosphite triesters upon reaction with various alcohols.
Two new types of sterically hindered chiral oxazaphosphorinanes 135 and 146 were then synthesized from cholesterol and camphor respectively. These structures, derived from $ gamma$-aminoalcohols possessing a tertiary alcohol function, could be isolated and characterized. They revealed very reactive in acidic conditions and led to rearrangements.
Finally, oxazaphosphorinane 188 derived from 1,2-O-isopropylidene-D-xylofuranose, was synthesized and characterized. The introduction of a participating group adjacent to the leaving phosphorothioate group led to the fast release of the phosphorothioate moiety. This new chiral auxiliary was successfully used as a precursor in the diastereoselective synthesis of a T-T phosphorothioate dimer, in a diastereomeric ratio of 28.5:1.* ftn*Please refer to dissertation for diagrams.
