Synthesis, structure, and properties of new spirooxindolodibenzodiazepine derivatives

An acid-catalyzed reaction of 3-(2-aminophenylamino)-5,5- dimethylcyclohexen-1-one with isatines leads to the formation of the earlier undescribed 3,3-dimethyl-2,3,4,5,10,11- hexahydrospiro[1H-dibenzo[b,e][1,4] diazepine-11,3-2H-indole]-1,2-dione derivati
