Desymmetrization of prochiral anhydrides with Evans' oxazolidinones: An efficient route to homochiral glutaric and adipic acid derivatives

The prochiral recognition between enantiotopic carbonyl groups in the reaction of 3-substituted glutaric and 3,4-disubstituted adipic anhydrides with anions of Evans' oxazolidinones has been investigated. Each of the σ-symmetric anhydrides provided a diastereoisomeric mixture of half-acids which were separated either by fractional crystallization or by column chromatography of their esters. The diastereoselectivity of the desymmetrization reaction is dependent on the substituents present in the anhydrides.

A silicon controlled total synthesis of the antifungal agent (+)-preussin

A stereoselective total synthesis of (+)-preussin has been achieved from a meso anhydride featuring a dimethyl(phenyl)silyl group as a masked hydroxy group which also restricts elimination reactions, stereodirects hydrogenation and ester enolate alkylation, and facilitates Curtius reaction.
