Transition-metal or iodine catalyzed transformations of O-acyl oximes to various N-heterocycles are well established. Herein, we report a catalyst free, oxime carboxylate based, three-component condensation method to access mono- and disubstituted pyrimidines. A broad range of substituted pyrimidines were prepared in moderate to excellent yields. Control experiments reveal that in situ generated formamidine is the key intermediate.

An organocatalytic inverse-electron-demand Diels-Alder reaction of ketones with 1,3,5-triazine through enamine catalysis has been developed. This method could furnish 4,5-disubstituted pyrimidines in good yields and high levels of regioselectivities.

Georgescu, Emilian,Georgescu, Florentina,Draghici, Constantin,Cristian, Liliana,Popa, Marcel Mirel,Dumitrascu, Florea
, p. 851 - 857 (2014/03/21)
A simple, clean and rapid one-pot three component, microwave-assisted synthesis of pyrrolo[1,2-c]pyrimidine derivatives starting from various substituted pyrimidines, 2-bromoacetophenones and nonsymmetrical, electron deficient alkynes in 1,2-epoxybutane which acts both as solvent and acid scavenger is reported. This one-pot three component synthesis implies short reaction times being at the same time highly cost-effective and environmental friendly.

, p. 2739 - 2748 (2007/10/02)
The synthesis of the title compounds 4 and 9 is described.In contrast to hexa-m-phenylene (6) 4,4''',6,6'''-tetrazahexa-m-phenylene (4) is planar.This is explained by less Pitzer strain in the outer sphere of 4.From 4 a tetranitro derivative (7c) was obta
