- Abstract
Nano-titania sulfuric acid (TSA) and boric acid [B(OH)3] were efficiently utilized for domino Knoevenagel-Michael-cyclocondensation reaction of malononitrile, various aldehydes and barbituric acid derivatives to synthesis of pyrano[2,3-d]pyrimidine diones. It is interesting that in boric acid aqueous solution system, H+ which abstracted from water by the interaction with B(OH)3, efficiently catalyzed the reaction.
