Two protocols for synthesis of series of low-molecular-weight di- and tri-substituted pyrimidines bearing a functional group at the 4th position, which rely on a base-mediated condensation of amidines or guanidines with β-alkoxyvinyl α-keto esters, have been developed. This approach allowed for multigram preparation of novel pyrimidine-4-carboxylates in 21–90% yield. The synthetic utility of these compounds was demonstrated by some standard functional group transformations providing promising building blocks for organic synthesis and drug discovery.

1,3,4,6-Tetrachloro (TCDGU) and 1,3,4,6-tetrabromo-3α,6α-diphenylglycolurils smooth halogen oxidizers have been exploited in a new direction as reagents for free radical substitution toward some N-halosuccinimide nonreactive bis-heterocycles. An unexpected selectivity and reactivity were observed with methyl benzenes, methyl heterocycles, and methyl-bis-heterocycles of interest. A chemometric study has been performed to optimize five independent factors of the chlorination reaction with TCDGU. The predictive model was established either for the halogenation conversion and the ratio of monochlorination.

The reaction of 2- and 6-methylpyrimidine 1-oxides with phosphoryl chloride underwent the selective side-chain chlorination to give 2- and 6-chloromethylpyrimidines as sole products.No by-products such as 2-chloro- and 4-chloropyrimidines were obtained ev
