Synthesis of novel derivatives of 2-amino-4 H-chromene is reported via three-component
reaction of 2, 4-dihydroxybenzophenone, malononitrile, and aromatic aldehydes in the …

An efficient synthesis of β-aryl-β-mercapto ketones is achieved via a tandem aldol
condensation-thia-Michael addition process using an aqueous medium and diethylamine …

Herein we demonstrate a novel tandem aldol condensation-thia-Michael addition process
using a bimetallic catalyst (ZrCl 4: Mg (ClO 4) 2). The novel bimetallic catalyst performs …
