Synthesis of Novel Dibenzo[3,4:7,8][1,5]diazocinoquinazolinones

Abstract A facile one step synthesis of dibenzo[3,4:7,8][1,5] diazocino[2,1-B:6,5-B′]diquinazolin-10,21-dione (4A) and N-methyl/ethyldibenzo[3,4:7,8][1,5]diazocino[6,5-B]quinazolin-5,16-diones (4B,C) is described. The mechanism involves a transannular reaction and the conformational structure of 4B...

Zusammenfassung:Abstract A facile one step synthesis of dibenzo[3,4:7,8][1,5] diazocino[2,1-B:6,5-B′]diquinazolin-10,21-dione (4A) and N-methyl/ethyldibenzo[3,4:7,8][1,5]diazocino[6,5-B]quinazolin-5,16-diones (4B,C) is described. The mechanism involves a transannular reaction and the conformational structure of 4B was confirmed by X-ray crystallographic data.
