Abstract
Enantioselective synthesis of crotyl geminal bis(silane) 4 has been developed by an asymmetric [1, 5]-hydride shift of allylic hydrazine. SnCl4-promoted Sakurai allylation of (R)-4 with acetals leads to chemoselective desilylation of SiMe3, generating E-syn-(S, R)-5 in good yields with high E/Z-, diastereo- and enantioselectivity.
