QSAR analysis of 2-oxo-1,2,3,4-tetrahydropyrimidine analogues of antibacterials

QSAR analysis of two sets of analogues of 2-oxo-1,2,3,4- tetrahydropyrimidine was performed to investigate the relationship between their physicochemical parameters and antibacterial activity. Predictive and statistically significant models were generated

Synthesis and reactions of some pyrimidine derivatives

Three different series of compounds including N-formylated thioxopyrimidines 3a-d, thiazine derivatives 4a-c and N-formylated oxopyrimidines 5a-d were synthesized by reaction of an appropriate ethyl 6-methyl-4-aryl-2-thioxo-1,2,3,4-tetrahydropyrimidine-5-

A mild and practical method for the regioselective synthesis of N-acylated 3,4-dihydropyrimidin-2-ones. New acyl transfer reagents

The treatment of 3,4-dihydropyrimidin-2-ones with n-BuLi at -78 °C, followed by quenching with various electrophiles furnished N3-substituted derivatives, regioselectively. Further, N1,N3-diacyl derivatives were found to transfer N1-acyl groups to nucleop

Metalation of Biginelli compounds. A general unprecedented route to C-6 functionalized 4-aryl-3,4-dihydropyrimidinones

4-Aryl-6-methyl-3,4-dihydro-2(1H)-pyrimidinone esters (DHPMs) readily undergo metalation at the C-6 methyl (vinylogous ester) position on treatment with lithium diisopropylamide at -10 °C. The resulting anion intermediates can be treated with electrophili

Synthesis and Reactions of "Biginelli-Compounds". Part I

Various reactions of 2-oxo (or thioxo)-1,2,3,4-tetrahydropyrimidine-5-carboxylic acid derivatives (Biginelli-compounds) were investigated.The site of methylation and acylation on 6-methyl-4-phenyl-2-thioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylic acid ethyl ester 1a and its 2-oxo derivative 9a was studied.The synthesis of pyrimidothiazines and thiazolopyrimidines was accomplished by condensation of 1a with 1,3- and 1,2-dielectrophiles.A Dimroth-like rearrangement yielding 6H-1,3-thiazines can be observed when 1a was treated with dimethylformamide and phosphorus oxychloride.The formation of indenopyrimidines can be achieved by intramolecular Friedl-Crafts acylation of 9a and 13, respectively.Finally a route for the preparation of 4,6-disubstituted-pyrimidine-5-carbonitriles is presented, starting with Biginelli-compound 25.
