Microwave assisted, Mont. K10 clay catalyzed solvent-free green synthesis of thiadiazine and quinazolinone derivatives from pyrazole aldehydes and 2-amino amides
Montmorillonite K10 has been found as a green catalyst for the synthesis of cyclized thiadiazine and quinazolinones derivatives under microwave irradiation and solvent free condition. The scope of the reaction has been demonstrated for a number of pyrazole aldehyde with O-aminoamides such as 2-amino sulfonamide and 2-amino benzamide. The reaction afforded a title compounds within few minutes of irradiation in excellent yield. Synthetic utility of 2-(1,3-diphenyl-1H-pyrazol-4-yl)-6-iodo-2,3-dihydroquinazolin-4(1H)-one has been demonstrated by synthesizing 2-(1,3-diphenyl-1H-pyrazol-4-yl)-6-phenyl-2,3-dihydroquinazolin-4(1H)-one under Suzuki coupling reaction protocol.A plausible mechanism for the formation of product is provided.
