Synthesis of Pyrazolone Derivatives. X. Synthesis of 2, 4, 6-Trioxohexahydro-5-pyrimidinyl Derivatives

Abstract

As a part of studies on syntheses of pyrazolone derivatives, syntheses of 1-phenyl-2-methyl-3(or 4)-[(5-substituted-2, 4, 6-trioxohexahydro-5-pyrimidinyl) methyl]-4(or 3)-substituted-3-pyrazolin-5-one were described.
