Abstract

ABSTRACT: Stirring an equimolar mixture of ninhydrin1 and 2-aminochromen-4-ones2 in CH3 COOH at room temperature produced 6a, 11a-dihydroxy-6 H -chromeno[2, 3- b ]indeno[2, 1- d ]pyrrole-11, 12(6a H, 11a H )-diones3, which on heating with aromatic amines6 in acetic acid produced 11b-hydroxy-7- N -arylimino-6 H -chromeno[2, 3- b ]isoindolo[1, 2- e ]pyrrole-12, 13(11b H )-diones7 .
