Abstract

A novel enzyme-catalyzed Biginelli reaction of acetoacetate, aromatic aldehyde and urea (thiourea) was described. Great acceleration of the one-pot multicomponent reaction was observed by the aid of enzymes. Various dihydropyrimidiones were prepared in good yields under the conditions using trypsin from porcine pancreas as the catalyst.
