The condensation of (1 R,2S) or (lS,2S)-N,N'-dimethyI-l-phenylpropane-l 2-diamines with aldehydes gives respectively two diastereorneric 2-alkyl-l,3,4-trimethyI-S-phen limidazolidines. At thermodynamical equilibrium the major isomer in the erythro series is this one where t f ! e substituents at pos
