The X-ray crystallographic study of the title compound, C 24 H 20 ClN 3 OS, clearly demonstrates that 1,3-dipolar cycloaddition occurs at the C N double bond of the 1,5benzodiazepine.
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
