Trifluoroacetic acid catalyzed dibenzodiazocine synthesis: Optimization and mechanism study

Dibenzo[b,f][1,5]diazocines, a class of potential building blocks for novel electrochemical actuators, were synthesized via a novel, efficient acid-catalyzed reaction of 2-acylbenzoisocyanate at room temperature. Real-time NMR analysis and the captured intermediate showed the mechanism was an unprecedented cyclization of the isocyanate with the neighboring acyl group, followed by the dimerization.

A New Synthesis of Naphthopyrroles. Conversion of Naphthothiophene-4,9-diones to Naphthopyrrole-4,9-diones.

A series of 2-substituted-4,9-dihydronaphthopyrrole-4,9-diones was prepared by the reaction of 4,9-dihydronaphthothiophene-4,9-diones with primary amines under mild conditions.The presence of halogen in the naphthothiophene-4,9-dione and the presence of hydroxyl, ether, or tertiary amine functions in the amine reagent do not interfere with the course of the reaction.
