| 摘 要： | A heteropolyacid efficiently catalyzed the cyclocondensation reaction of 2‐aminobenzamide and salicylamide with aldehydes and ketones to afford good yields of benzoxazine and quinazoline ring systems in an aqueous medium. The method gives clean reactions, has simple workup procedure, and uses environment friendly conditions. |
