inhibited PfGSK-3, with four of these compounds exhibiting IC50 values in the sub-micromolar range (0.00048–0.440 µM). Evaluation of the structure-activity relationships required for PfGSK-3 selective inhibition indicated that a C6-OCH3 substitution on ring A is preferred, while the effect of the ring B substituent on activity, in decreasing order is: C4′-CN > C4′-F > C3′-OCH3 > C3′,4′-diCl. To date,

Thirty benzofuran-2-yl(phenyl)methanones 1–30 were synthesized and characterized their structures by spectroscopic techniques. Substituted phenacylbromide and different derivatives of 2-hydroxy-benzaldehyde treated in the presence of anhydrous K2CO3 in acetonitrile at room temperature to afford the desired benzofurans 1–30. All compounds were screened for their in vitro α-amylase inhibitory and radical

3]thiazoles are described from readily accessible α-tosyloxyketones and mineral oxides in processes that are accelerated by exposure to microwaves. The 2-aroylbenzo[b]furans are readily obtained from salicylaldehydes and α-tosyloxyketones in the presence of solid potassium fluoride doped alumina (KF–Al2O3) whereas montmorillonite K-10 clay provides 1,3-thiazoles from thioamides and α-tosyloxyketones

Abstract An efficient and convenientsynthesis of benzofurans has been described from phenacyl halides and o-hydroxy benzaldehyde in the presence of DABCO. The procedure is applicable for a variety of phenacyl halides and provide a variety of benzofurans. DABCO act as a base and as well as nucleophile. GRAPHICAL ABSTRACT
