Enantioselective synthesis of SiMe/SiPhMe-substituted crotyl geminal bis(silane) has been developed. This compound is a useful reagent for PhCB(CF)-catalyzed asymmetric Sakurai allylation and one-pot Sakurai allylation/Prins cyclization processes. Chemoselective desilylation of SiPhMe leads to efficient chirality transfer.
