Deep eutectic solvent mediated synthesis of quinazolinones and dihydroquinazolinones: Synthesis of natural products and drugs

Ghosh, Suman Kr,Nagarajan, Rajagopal

, p. 27378 - 27387 (2016/04/04)

A mild and greener protocol was developed to synthesize substituted quinazolinones and dihydroquinazolinones via deep eutectic solvent (DES) mediated cyclization with a series of aliphatic, aromatic, and heteroaromatic aldehydes in good to excellent yields. This greener strategy was further utilised to synthesize various quinazolinone natural products and drugs.
