A short and efficient Julia-Kocienski olefination protocol, based upon the use of chelating agents (18-crown-6 or TDA-1 for K+; 12-crown-4 or HMPA for Li+), was developed. This protocol enhances the (E)-selectivity of the reaction an
HIGHLY ENANTIOSPECIFIC AND ERYTHRO-SELECTIVE -WITTIG REARRANGEMENT OF ENANTIOMERICALLY ENRICHED ALLYLIC BENZYL ETHERS. A NEW, FORMAL CHIRAL SYNTHESIS OF l-EPHEDRINE

The -Wittig rearrangement of chiral (Z)-allylic benzyl ethers provides 94-97percent of asymmetric transfer (enantiospecificity), along with 90-96percent of erythro-selectivity.Its synthetic potential is illustrated through the stereocontrolled synthe
