Autor: Suhas Shinde, Shrinivas P. Charate, Sharda E. Kondawar, Uday V. Desai, Prakash P. Wadgaonkar, Chandrashekhar V. Rode

Publikováno v: Journal of the Indian Chemical Society. 98:100090

Solvent-free carbonylation of glycerol with urea to glycerol carbonate (GC) was achieved over heterogeneous Cu–Zn mixed oxide catalyst. Cu–Zn catalysts with different ratios of Cu:Zn were prepared using co-precipitation (CP) and oxalate gel (OG)

We describe here our journey from the failure of our attempts in controlled oxidation of sulfides to sulfoxides using an Oxone®–KBr combination to our success in the development of a catalyst-free protocol for the oxidation of sulfides to sulfoxid

A series of spirochromene-tethered 1,2,3-triazoles (1,2,3-triazolylspirochromenes) were designed and synthesized via click-chemistry-based one-pot five-component reaction between N-propargyl isatins, malononitrile, dimedone (or 4-hydroxyl-6-methyl-2H

Diethylamine Dess–Martin periodinane: an efficient catalyst–oxidant combination in a sequential, one-pot synthesis of difficult to access 2-amino-3,5-dicarbonitrile-6-sulfanylpyridines at ambient temperature

Autor: Ravindra V. Kupwade, Uday V. Desai, Makarand A. Kulkarni, Prakash P. Wadgaonkar, Supriya S. Khot

Publikováno v: RSC Advances. 7:38877-38883

Herein, diethylamine Dess–Martin periodinane has been demonstrated for the first time as an efficient catalyst–oxidant combination in a sequential, one-pot synthesis of medicinally privileged but difficult to access 2-amino-3,5-dicarbonitrile-6-s

Sulfamic acid-catalyzed, environmentally benign synthesis of bis-tetronic acids at ambient temperature

Autor: Kisan M. Kodam, Prakash P. Wadgaonkar, Uday V. Desai, Kapil S. Pandit

Publikováno v: Research on Chemical Intermediates. 43:141-152

An enviro-economic protocol has been described for the synthesis of bis-tetronic acids by pseudo-three-component condensation between aldehydes/isatins and tetronic acid using sulfamic acid as a solid acid catalyst. Easy commercial availability of th
