We report bleaching earth clay pH 12.5/PEG-400 as an efficient catalytic system for preparation of α,β-unsaturated ketones (chalcones). The method presents one or more advantages over existing methodologies such as shorter reaction time, excellent

The cross-aldol condensation between isatin (I) and substituted acetophenone (IIa–e) in one-pot reaction afforded 3-[2-(substituted-phenyl)-2-oxo-ethylidene]-1,3-dihydro-indol-2-one using polyethylene glycol (PEG-400) as solvent and bleaching earth

A novel series of indeno-benzothiazepine derivatives was synthesised via a “green” route. Synthesis of these compounds involves the treatment of dinucleophiles such as 2-aminobenzenethiols with α,β-unsaturated ketones in poly(oxyethylene) (poly
