The three possible structural isomers of 4-(pyridyl)pyrimidine were employed for the synthesis of new pyrrolo[1,2-c]pyrimidines and new indolizines, by 1,3-dipolar cycloaddition reaction of their corresponding N-ylides generated in situ from their corresp
One-pot and three-component synthesis of substituted pyrimidines catalysed by boron sulfuric acid under solvent-free conditions

An efficient, simple and one-pot synthesis of pyrimidine derivatives by a three-component reaction of ketones, triethyl orthoformate, and ammonium acetate in the presence of boron sulfuric acid as a reusable and efficient catalyst under solvent-free conditions is reported. The reusability of catalyst, simplicity of the starting materials, short reaction time, one-pot, and good yields of products are the main advantages.

N,N,N',N'-Tetrabromobenzene-1,3-disulfonamide was used as an efficient catalyst for the one-pot synthesis of pyrimidine derivatives in excellent yields from triethoxymethane, ammonium acetate, and various ketone derivatives at 100-110 °C under solvent-fre

The ring transformation of nitropyrimidinone 1 with acetophenone derivatives 2 affords two kinds of azaheterocyclic compounds, 4-phenylpyrimidines 3 and 3-nitro-6-phenyl-2-pyridones 4. On the basis of the relationship between electronic properties of the substituent and ratios of products, a plausible reaction mechanism is provided. Furthermore, the present reaction could be applied to heterocyclic ketones giving bihetaryl compounds.
Photochemical ring contraction of 4-heteroaryl-substituted 1,4(or 3,4)-dihydropyrimidines into imidazoles
Stoel, R. E. van der,Plas, H. C. van der,Jongejan, H.
, p. 364 - 367 (2007/10/02)
Photolysis of 4-R-1,4(or 3,4)-dihydropyrimidines causes ring contraction into imidazoles, provided that the substituent R is capable of sufficiently stabilizing an anionic centre (R=2-thiazolyl, 2-pyridyl, 4-pyridyl).Chemical evidence is presented to show
