| Abstract: | Synthesis and characterization of 3H, 9H, 10H, 10aH-10-aryl-2-aryliminothiazolidino[4,5-b][1,5]benzodiazepines and their alkoxyphthalimide derivatives are described. Cyclization of 5-arylidene-2-aryliminothiazolidin-4-ones 1a-i with o-phenylenediamine in xylene furnishes the corresponding 1,5-benzodiazepines 2a-i. In another reaction route, 1a-i when condensed with ω-bromoalkoxyphthalimides 3a-c give 3-alkoxyphthalimido-5-arylidene-2-aryliminothiazolidin-4-ones 4a-a' which on cyclization with o-phenylenediamine produce 9H, 10H, 10aH-3-N-(n-alkoxyphthalimido)-10-aryl-2-aryliminothiazolidino[4,5-b][1,5]benzodiazepines 5a-a' in good yields. |
