摘要:
Reaction of the cyclic carbonates of acyclic vinyl diols with RCu(CN)Li.BF3, RCu(CN)MgBr-BF3, or RMgBr.CuI (cat) in THF at -78-degrees-C proceeded in S(N)2' fashion and resulted in the formation of alkylated (E)-allylic alcohols with remarkably high diastereoselectivity. This reaction represents an efficient 1, 3-chirality transfer method.
