Stereodivergent synthesis of two diastereoisomeric enoates by asymmetric horner–wadsworth–emmons reaction using a single chiral auxiliary
Abstract
Stereodivergent synthesis of both diastereoisomeric enoates, including vinylogous acids, is achieved in the kinetic resoultion of branched aldehydes and asymmetrization of prochiral cyclic ketone by chiral phosphorus reagents derived from (–)-8-phenylmenthol.
