Amino-Functionalized MCM-41 base-Catalyzed one-Pot synthesis of 2-Amino-5,6-dihydropyrimidin-4(3H)-ones
摘要:
A simple and efficient one-pot method for the preparation of 2-amino-5,6-dihydropyrimidin-4(3H)-one from the cyclocondensation of Meldrum's acid, aldehydes and guanidinium carbonate using a catalytic amount of amino-functionalized MCM-41 is described. This efficient technique has the advantage of giving 2-NH2-DHPM building blocks using a base catalyst in good to high yields, being completed in short reaction times and offering a simple product isolation procedure.
nanocomposite catalyzed procedure for the synthesis of 2-amino-6-aryl-5,6-dihydro-4(3H)-pyrimidinones from a one-pot threecomponent coupling reaction of Meldrum’s acid, aromatic aldehydes, and guanidine nitrate with high yields under solvent-free conditions. This new protocol has revealed several advantages such as recyclability of catalyst, short reaction times, high to excellent yields of products
