| 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. |
