Synthesis, characterization and antimicrobial activity of novel ethyl 1-(N-substituted)-5-phenyl-1H-pyrazole-4-carboxylate derivatives

In the present study, a novel series of Pyrazole derivatives (3a-m) were synthesized by condensing ethyl-3-(dimethylamino)-2-(phenylcarbonyl)prop-2- enoate with different aromatic and aliphatic hydrazines. These newly synthesized compounds were characteri

New reactivity of nitropyrimidinone: Ring transformation and N-C transfer reactions

Nitropyrimidinone 1 revealed new reactivity upon treatment with active methylene compounds 2 under basic conditions. The N1-C2-C3-C4 moiety of 1 combined with two carbon units of 2 affording polyfunctionalized pyridones 4, which was hitherto unknown ring transformation. On the other hand, the N1-C2 moiety of 1 was transferred to the methylene group of 2 giving functionalized enamines 3. It was also possible to modify the amino group in 3a by reactions with primary amines. Enamines 3 reacted with hydrazines, and leading to functionalized pyrazoles 7 quantitatively. The ratios of regioisomeric pyrazoles 7/8 were moderately controlled by use of sterically hindered enamines 3h, 3k and 31. Furthermore, enamine 3a was readily converted to 1,4-diazepines 9 having a functional group at the 6-position.

Novel generation of azomethine imines from α-silylnitrosamines by 1,4- silatropic shift and their cycloaddition

Novel and facile generation of azomethine imines from α- silylnitrosamines and subsequent cycloaddition with dipolarophiles leading to a variety of pyrazole derivatives have been developed. The key to the reaction is a 1,4-silatropic shift caused by stron

A CONVENIENT SYNTHESIS OF 2-PYRAZOLINES AND PYRAZOLES FROM ALDEHYDE HYDRAZONES AND ETHYL PROPIOLATE

Aldehyde methylhydrazones (3) reacted with ethyl propiolate in the presence of acetic acid affording 4-ethoxycarbonyl-1-methyl-2-pyrazolines (4) in 13-44percent yields.Easily 4 was dehydrated to the corresponding pyrazoles (6) by treatment with H2O2 in the presence of FeCl2.
