A novel synthesis of highly enantioenriched dipeptides containing homophenylalanine is described. The process involves a crystallisation-induced asymmetric transformation (CIAT) in a Michael addition followed by exhaustive reduction. A unique example of a formally stereodivergent CIAT in conjugate addition of an achiral N-nucleophile to enantiomerically pure Michael acceptor has been discovered. (C) 2010 Elsevier Ltd.

Adducts of the conjugate addition of benzylamine to enantiopure amides of aroylacrylic acid possess high enantiomeric and diastereomeric purity. A high degree of stereoselectivity has been achieved by means of crystallization-induced asymmetrictransformation. A practical synthesis leading to dipeptides containing homophenylalanine is depicted.
