名称:
Very high chemoselective, regioselective, and E-stereoselective 1,3-chirality transfer involving reaction of acyclic (E)- and (Z)-.gamma.-mesyloxy .alpha.,.beta.-enoates and organocyanocopper-trifluoroborane reagents. Efficient synthetic routes to functionalized chiral .alpha.-alkyl (E)-.beta.,.gamma.-enoates and (E)-allylic alcohols with high optical purity
