Aminoalcohols V [1]: A method for the synthesis of enantiomerically pure ring-chlorinated epinephrines and norepinephrines

The synthesis of enantiomerically pure 5-and 6-chloroepinephrine hydrochloride, resp., as well as 6-chloronorepinephrine hydrochloride is described starting from ring chlorinated O-benzylated dihydroxybenzaldehyde cyanohydrins, which are O-protected using
