Studies of the asymmetric [2+2] cycloaddition of silylketenes and aldehydes employing Ti-TADDOL catalysts

Ti-TADDOL catalysts provide good reactivity and moderate enantioselectivity in the asymmetric [2+2] cycloaddition of silyl ketenes and aldehydes. The effects of potential bidentate chelation of benzyloxy substituted aldehydes and of the steric size of the ketene silyl group were studied.

A new approach to the preparation of 2-substituted tetrahydrofurans with alpha-syn selectivity

A strategy for selectively preparing 2-substituted tetrahydrofurans bearing α-syn side chain stereochemistry, based on intramolecular 2-oxetanone ring opening, has been demonstrated. A new approach to the preparation of 3,4-disubstituted 2-oxetanones is also presented.

SYSTHESIS AND INTRAMOLECULAR RING CLEAVAGE OF 2-OXETANONES

Intermolecular 2+2 aldehyde-ketene cycloaddition, followed by Lewis acid induced intramolecular ring opening of the 2-oxetanone product have been used to prepare tetrahydrofuran and tetrahydropyran ring systems.
