N-SUBSTITUTED NOREPHEDRINE CHIRAL DERIVATIVES, THEIR PREPARATION AND THEIR USE FOR THE SYNTHESIS OF OPTICALLY ACTIVE FUNCTIONALISED COMPOUNDS BY HYDROGEN TRANSFER

摘要

A ligand adapted for use in a process for enantioselective reduction of unsaturated compounds carrying functional groups by a hydrogen transfer method including an optically active N-substituted chiral derivative of norephedrine and the associated process.
