Abstract: 2a, 4-Disubstituted 5-benzoyl-2-chloro/-2,2-dichloro-2a,3,4,5-tetrahydro-azeto[1, 2-a] [1,5]benzodiazepin-1 (2H)-ones (3a-h) were synthesized by cycloaddition reactions of 2,4-disubstituted 1-benzoyl-2,3-dihydr o-1H-1,5-benzodiazepines(2a-h) and ketenes, generated from chloroacetyl chloride or dichloroacetyl chloride in the presence of triethylamine, in anhydrous benzene. In some cases, ring contraction of benzodiazepines has also been observed.
