Microwave irradiation: Novel and facile methods for the synthesis of new pyrimidinones
摘要:
We describe here a rapid process for the preparation of new 9-chloromethyl-12-aryl-10.12-dihydrobenzo[5.6]chromeno[2,3-d]pyrimidin-11-ones 5a-d and 10-chloromethyl-7-aryl-7,9-dihydrobenzo[7,8]chromeno[2,3-d]pyrimidin-8-ones 6a-d by two different methods utilizing microwave irradiation. This methodology provides better yields (72%-80%) and high purity of the title compounds. (C) 2014 Fakher Chabchoub. Published by Elsevier B.V. on behalf of Chinese Chemical Society.
