Abstract: An efficient synthesis of a series of pyrazolopyridocoumarins is reported by condensation of 4-hydroxycoumarin, benzaldehydes and 1-alkyl-5-amino-pyrazoles in the presence of 10 mol% zinc chloride in ethanol under reflux conditions through one-pot reaction. The significant… read more here.

Abstract: Abstract A mild, catalytic method for the synthesis of 3-carboxy-2,5-disubstituted furans is reported proceeding via a 5-exo-dig cycloisomerization reaction. The iron(III) chloride-catalyzed transformation of aryl- and alkyl β-ketoesters enables synthetic access to functionalized furan core… read more here.

DOI: 10.1039/d1cc06439h
Abstract: The commercially available Lewis acid, 9-BBN and Lewis basic [Et4N]Cl are used as catalysts for the reduction of chlorophosphines R2PCl in the presence of phenylsilane. Aryl-chlorophosphines afford primarily diphosphines (P2R4) while secondary phosphines predominate for… read more here.

DOI: 10.1080/10406638.2019.1630653
Abstract: Abstract An efficient and clean method was developed for the three components, one-pot synthesis of pyrimidinone/thione derivatives using cyclopentanone, variety of aromatic aldehydes, and urea/thiourea by using cyanuric chloride catalyzed Biginelli-type reaction. The reactions proceed… read more here.
