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 rapid and efficient access to diaryldibenzo[b,f][1,5]diazocines

2-Benzoylbenzoyl azides undergo facile cyclization under acidic conditions to give substituted dibenzo[b,f][1,5]-diazocines in good yields. This approach shortens the synthetic steps toward these compounds as compared with conventional methods. The mechanism of the diazocine synthesis is assumed to proceed by an unprecedented intermolecular [2 + 2] cyclization.

Studies in Large Ring Compounds: Part V - Synthesis of 6,12-Diphenyldibenzodiazocines

Polyphosphate ester (PPE) has been found to be an elegant reagent for the synthesis of 6,12-diphenyldibenzodiazocines (IIa-e) from (2-aminophenyl)(aryl)methanones (Ia-e).
