A novel protocol for the Bismuth metal mediated regioselctive crotylation of aldehydes yielding α-homoallylic alcohols has been developed using 20 mol% [bmim][HSO4] as a metal activator, as well as...
Reaction of allylantimony with aldehydes provides homoallylic alcohols with high threo selectivity in the case of (E)-4-methyl-2-pentenylantimony (2c) and with preferential erythro selectivity in the case of crotylantimony (2a).
