Résumé : The condensation of (1R,2S) or (1S, 2S)‐N,N′‐dimethyl‐1‐phenylpropane‐1,2‐diamines with aldehydes gives respectively two diastereomeric 2‐alkyl‐1,3,4‐trimethyl‐5‐phenylimidazolidines. At thermodynamical equilibrium the major isomer in the erythro series is this one where the substituents at position 2 and 4 are ”cis“. In the threo series, the major isomer has the substituents at position 2 and 4 ”trans“. Copyright © 1990 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim
