Deep eutectic solvent-Catalyzed for the synthesis of ۲,۳- Dihydroquinazolin-۴(۱H)-ones as an efficient, cost-effective, and recoverable system

An efficient and environmentally benign one-pot component protocol has been presented for the synthesis of structurally diverse ,۳-Dihydroquinazolin-۴(۱H)-ones with aldehydes and ۲-aminobenzamide in a deep eutectic solvent (SnCl۲ : urea: ۱ : ۲). The present protocol offers some advantages such as operational simplicity with easy workup, shorter reaction times, good to excellent yields with superior atom economy and environmentally benign reaction conditions.
