SYNTHESIS AND SOME CONVERSIONS OF 6-METHYL- AND 1,6-DIMETHYL-5-NITRO-4-PHENYL-2-OXO-1,2,3,4-TETRAHYDROPYRIMIDINES

Article abstract of DOI:10.1007/BF00531510

Using a modification of the Biginelli reaction, we have synthesized 6-methyl- and 1,6-dimethyl-5-nitro-4-phenyl-2-oxo-1,2,3,4-tetrahydropyrimidines. We have studied some of their chemical conversions involving the methyl group on the C₍₆₎ atom, the nitrogen atoms of the pyrimidine ring, and the phenyl substituent.
