Asymmetric epoxidation of (E)-3-trialkylsilyl-2-propen-1-ols gives the expected epoxides with high enantioselectivity. Ring opening reactions of these epoxides with organocopperreagents furnishes 1,2-diols which are readily cleaved with Pb(OAc)4 to afford α-silyl aldehydes with no detectable loss of stereochemistry.
