چکیده
|
Synthesis of 2,3-dihydroquinazolin-4(1h)-ones using h3bo3/montmorillonite k10 (h3bo3/mont k10) catalyst has been reported. h3bo3/mont k10 and h3bo3/mont k30 have been prepared and used as catalysts in the reaction between anthranilamide and benzaldehyde to prepare 2-phenyl-2,3-dihydroquinazolin-4(1h)-one. the catalysts have been characterized for their physico-chemical properties by xrd, ir, bet surface analysis, tga, sem, and drifts. h3bo3/mont k10 has shown better catalytic activity among the catalysts tested for the synthesis of 2-phenyl-2,3-dihydroquinazolin-4(1h)-one. the reaction conditions have been optimized for 2-phenyl-2,3-dihydroquinazolin-4(1h)-one and the reusability of h3bo3/mont k10 has also been investigated. several 2,3-dihydroquinazolin-4(1h)-one derivatives have been synthesized in good to excellent yields using the optimized reaction conditions
