Optically active silyl and stannylsubstitutedcyclopropylmethanols were effectively obtained by the catalytic and enantioselective cyclopropanation of γ-silyl and γ-stannyl substituted allylic alcohols with Et2Zn and CH2I2 in the presence of chiral N,N′-bis(p-nitrobenzenesulfonyl)-1,2-cyclohexanediamine in good enantioselectivites. The absolute configurations of the resulting metallocyclopropanes
