An efficient ultrasound-promoted method for the one-pot synthesis of 7,10,11,12-tetrahydrobenzo[c]acridin-8(9H)-one derivatives
摘要:
A new, efficient and general method for preparation of 7,10,11,12-tetrahydrobenzo[c]acridin-8(9H)-one derivatives using ultrasound irradiation is reported. Under ultrasound, the reaction time is short, the yields are high and the reaction conditions are mild. (c) 2009 Elsevier B.V. All rights reserved.
A series of 7-aryl-7,10,11,12-tetrahydrobenzo[c]acridin-8(9H)-one derivatives were synthesized via the three-component coupling from aromatic aldehydes, 1-naphthylamine, and 5,5-dimethylcyclohexane-1,3-dione catalyzed by stannous chloride dihydrate (SnCl2 center dot 2H(2)O) under ultrasonic irradiation at room temperature. The products were isolated in good yields within short reaction times.
