Abstract
The treatment of 4-sulfonyl derivatives of 5-phenyl-1,3,4,5-tetrahydro-1,4-benzodiazepin-2-ones (I) with base was shown to result in the formation of 1,3-dihydro or 1,5-dihydro-1,4-benzodiazepin-2-ones (III and II respectively) depending upon the conditions used. The base treatment of 1-sulfonyl substituted 2,3-dihydro-1,4-benzodiazepines (V) was shown to give the vinylimines VI.
