Abstract: An efficient microwave-assisted one-pot procedure has been proposed for thesynthesis of new 4-aryl-6-(methylamino)-5-nitro-2-(1H-pyrrol-2-yl)-4H-pyran-3-carbonitriles by condensation of 3-oxo-3-(1H-pyrrol-2-yl)propanenitrile with (E)-N-methyl-1-(methylsulfanyl)-2-nitroethenamine and substitutedbenzaldehydes in the presence of a catalytic amount of piperidine using ethanolas a solvent. The transformation occurs via successive Knoevenagel condensation,Michael addition, and intramolecular cyclization. The proposed procedure isadvantageous due to its one-pot mode, short reaction time, simple purificationby recrystallization, and excellent yields. The product structure was confirmedusing various spectroscopic techniques, including IR,1H and 13C NMR, LC/MS,elemental analysis, and single crystal X-ray diffraction study. The synthesizedcompounds were evaluated for their anticancer activity against 60 differenthuman cancer cell lines in nine cancer panels, and two compounds were found tobe potent against different cell lines.

A simple and efficient method for the synthesis of 3-oxopropanenitriles from variously substituted heterocyclic compounds via direct electrophilic cyanoacetylation is described. A series of heterocyclic 3-oxopropanenitriles (2a, 2b, 2c, 2d, 2e, 2f, 2g, 2h, 2i, 2j, 2k) have been synthesized using mixed anhydride (acetic or trifluoroacetic anhydride:cyanoacetic acid) in the presence of Mg(ClO4)2·2H2O as catalyst. This method can be extended also for the cyanoacetylation of electron poor aromatic compounds.

We report the discovery of a series of acrylonitrile-containing molecules and α-amino amides which cause 99-100% lethality in H. contortus. Of the 22 acrylonitrile analogues investigated, the most active were 2-cyano-3-[1-(3-dimethylaminopropyl)-2-methyl-

The synthesis of 2-(tetrazol-5-yl)-2H-azirines is reported for the first time. Using the Neber approach, β-ketoxime-1H-tetrazoles were converted into the target 2H-azirines bearing phenyl, furan-2-yl, thiophen-2-yl, or pyrrol-2-yl substituents at C-3. It was demonstrated that the alkaloid-mediated Neber reaction allows the asymmetric synthesis of 2-(tetrazol-5-yl)-2H-azirines.
