摘要: Abstract An efficient synthesis of 3,4-dihydropyrimidine 2 (1 H )-ones and thiones (3,4-DHPMs) core was prepared by one-pot three-component Biginelli condensation which catalyzed trifluoromethane sulfonic acid. The classical Bignelli reaction has been extended the use N-substituted benzoxazolyl semicarbazides thiosemicarbazides this method advantage excellent yields short times.
