Abstract
Abstract Reaction of o-phenylenediamine 1 with dehydracetic acid 2 in different alcohols leads to 2-alkoxycarbonylmethyl 4-methyl 1,5-benzodiazepines 3–7 , to 4-acetyl methylene 1,5-benzodiazepin-2-one 8 , and to benzimidazoles 9 and 10 . This constitutes a novel and efficient synthesis of some benzodiazepine derivatives.
