In the title compound, C18H19N3O3, the tetrahydropyrimidone ring adopts a distorted boat conformation. In the crystal structure, intermolecular N—H...O hydrogen bonds link the molecules into centrosymmetric dimers, which are further linked via inte

Polyheterocyclic pyrimidinyltheophyllines have been synthesized from pyrimidine and theophylline precursors. Attempts to cyclize these reactive bis-heterocyclic systems resulted in the formation of the corresponding diazepine moieties. In addition, m

3-Cyanopyridine-2(1H)-thiones have been shown to react with Biginelli-type ethyl 4-aryl-6-(bromomethyl)-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylates upon heating in DMF giving rise to ethyl 4-aryl-6-{[(3-cyanopyridin-2-yl)thio]methyl}-2-oxo-1,2,

A one-pot synthesis of diethyl 4,4′-(1,4-phenylene)bis[6-(chloromethyl)-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylates] is proposed via three-component condensation of terephthalic aldehyde, 4-chloroacetoacetic ester, and ureas under Biginelli r

Benzotriazole-mediated routes to peptidomimetics and peptide conjugates have been discussed in detail. The Katritzky group developed a benzotriazole methodology toward the activation of carbonyl groups of amino acids and modified analogs, which allow

The three-component reaction of thiones (I) with aldehydes (II) and chloroacetic acid readily affords thiazolo[3,2-a]pyrimidines (IV), whilst prolonged reaction times leads to the formation of hydrolysis products (V).
