An efficient HCCP-mediated direct amination of quinazolin-4(3H)-ones
摘要:
An efficient direct amination of quinazolin-4(3H)-ones has been developed. Treatment of quinazolin-4(3H)-ones with HCCP, DIPEA, and N-contained nucleophiles in acetonitrile could be able to form the corresponding 4-aminoquinazoline derivatives. Under the optimal reaction conditions, the amination products were achieved in good yields. (C) 2011 Elsevier Ltd. All rights reserved.
An efficient rhodium(III)‐catalyzed site‐selective functionalization of 4‐anilinoquinazolines offers exciting possibilities for fused polycyclic 4‐anilinoquinazoline derivatives and N‐quinazoline‐indoles by using diazo compounds as the elegant coupling partners. This one‐pot cascade approach to establish various complex 4‐anilinoquinazoline units with potential biological activities only depends on

A new multi-component synthesis of 4-arylaminoquinazolines from the reaction of 2-aminobenzamide, orthoesters, and substituted anilines in the presence of catalytic amounts of Keggin-type heteropolyacids is reported. The effects of reaction conditions and different heteropolyacids have been studied. (C) 2008 Elsevier Ltd. All rights reserved.

A new synthesis of twelve 4-arylaminoquinazolines from 2-amino-N-arylbenzamidines and formic acid is described. The entering amidines were obtained in the reaction of anthranilonitrile with 50% molar excess of aromatic amines and anhydrous aluminium chloride. (C) 1998 Elsevier Science Ltd. All rights reserved.
