Desymmetrization of 3-dimethyl(phenyl)silyl glutaric anhydride with Evans' oxazolidinone: An application to stereocontrolled synthesis of the antifungal agent (+)-preussin

A stereoselective total synthesis of (+)-preussin (1) has been achieved from the a-symmetric 3-dimethyI(phenyl)silyl substituted glutaric anhydride 4 featuring its desymmetrization using Evans' oxazolidinone 10. The first homochiral intermediate, the glutarate half-ester 9 was obtained from both the diastereoisomeric acids lia, and 12a in a convergent fashion. The dimethyl(phenyl)silyl group is not only acting as a masked hydroxy group but also restricts elimination reactions, and facilitates Curtius reaction. It also stereodirects ester enolate alkylation of 18, and hydrogenation of intermediate Δ1-pyrroline 5.
