摘要

A three-step synthesis of pseudoephenamine suitable for preparing multigram amounts of both enantiomers of the auxiliary from the inexpensive starting material benzil is described. The sequence involves synthesis of the crystalline monomethylimine derivative of benzil, reduction of that substance with lithium aluminum hydride, and resolution of pseudoephenamine with mandelic acid.
