K2S2O8activation by glucose at room temperature for the synthesis and functionalization of heterocycles in water

While persulfate activation at room temperature using glucose has primarily been focused on kinetic studies of the sulfate radical anion, the utilization of this protocol in organic synthesis is rarely demonstrated. We reinvestigated selected K2S2O8-mediated known organic reactions that invariably require higher temperatures and an organic solvent. A diverse, mild functionalization and synthesis of heterocycles using the inexpensive oxidant K2S2O8 in water at room temperature is reported, demonstrating the sustainability and broad scope of the method. Unlike traditional methods used for persulfate activation, the current method uses naturally abundant glucose as a K2S2O8 activator, avoiding the use of higher temperature, UV light, transition metals or bases.

Aroylation of Electron-Rich Pyrroles under Minisci Reaction Conditions

The development of Minisci acylation on electron-rich pyrroles under silver-free neutral conditions has been reported featuring the regioselective monoacylation of (NH)-free pyrroles. Unlike conventional Minisci conditions, the avoidance of any acid that could result in the polymerization of pyrroles was the key to success. The umpolung reactivity of the nucleophilic acyl radical, generated in situ from arylglyoxylic acid, could help explain the mechanism of product formation with electron-rich pyrroles. Alternatively, the nucleophilic substitution of the acyl radical on the electron-deficient pyrrole radical cation is proposed.

Synthesis of a new compound family, 1-aryl-3H-pyrrolo[2,1-d][1,2,5] triazepin-4(5H)-ones

Representatives of a new family, 1-aryl-3H-pyrrolo[2,1-d][1,2,5]triazepin- 4(5H)-ones have been synthesized at our laboratory as bioisosters of biologically active 1-aryl-2,3-benzodiazepine-4-ones. The efficient synthetic route described applies the synth

Infrared and Nuclear Magnetic Resonance Properties of Benzoyl Derivatives of Five-membered Monoheterocycles and Determination of Aromaticity Indices

Benzophenones, 2-benzoylthiophenes, 2-benzoylpyrroles, and 2-benzoylfurans, which have substituents at m- and p-positions of the benzoyl ring were prepared and their ir and nmr spectra were obtained in 0.1 M chloroform-d solution. The chemical shift values of each series were plotted against the Hammett substituent parameters to give good correlation, with the exception of the ortho-Hs and -Cs. The slopes as well as the differences in chemical shift gave sets of meaningful values for the indices of aromaticy.

Zinc-mediated acylation and sulfonation of pyrrole and its derivatives

Pyrrole and its derivatives react smoothly with acid chlorides and sulfonyl chlorides in the presence of zinc metal in toluene at ambient temperature to afford the corresponding 2-acetyl and 2-sulfonyl pyrrole derivatives in high yields with high regioselectivity.

Pyrrolyl oxyphenyl ketones

4,5-Dihalopyrrol-2-yl oxyphenyl ketones, prepared either by Friedel-Crafts condensation of a 4,5-dihalopyrrole-2-carboxylic acid halide with an appropriate hydroxy or lower-alkoxy-substituted benzene or by condensation of a hydroxy or lower-alkoxy-substituted benzaldehyde with pyrrole in the presence of sodium hydride followed by halogenation, with elemental chlorine or bromine, of the resulting pyrrol-2-yl oxyphenyl ketone, useful as antibacterial and antifungal agents.
