摘要

We have recently reported that reductive metalation of allyl phenyl sulfides is a versatile and general preparative method for hydrocarbon allyl anions and that the latter, in the presence of titanium tetraisopropoxide, add in a 1, 2-fashion to enals only at the most substituted terminus of the allyl We now reveal simple procedures for securing 1, 2-addition to aldehydes and enals mainly at the least substituted terminus of such allyl anions, a unique ...
