Substituted α-silylacetic esters have been prepared in good yields and with reasonable diastereoselectivities by three different routes. The first two involved alkylation of the parent α-silylacetic ester enolates, with the chiral auxiliaries being present either on silicon or on the ester function. The third route involving asymmetric insertion of metal-carbenoids into the Si-H band was found to afford better diastereoselectivities, using pantolactane as chiral auxiliary.

α-silyl-α-substituted acetic esters have been prepared in good yields and reasonable diastereoselectivities using an asymmetric metal carbene insertion into the Si-H bond. Optically active 1,2-diols were then prepared after reduction of the ester and conv
