摘要

Recently, we have reported on the effect of conjugative electron-withdrawing groups and α-anion-stabilizingheteroatom substituents that distribute charge through a double bond, on the configurational stability of chiral carbanions.1 The effects can be estimated on the basis of the extent of chirality transfer induced by intramolecular trapping during [2,3]-Wittig rearrangement2 of chiral 3-substituted1-phenyl-1-propenyloxy-2-propen-1-yl carbanions ...
