Reaction of Chalcones with NBS, a Simple One Pot Synthesis of 2-Aroylbenzo[b]furanes
A simple one pot synthesis of 2-aroylbenzo[b]furanes has been achieved by bromomethoxylation with NBS and subsequent treatment of the appropriately substituted 2-hydroxychalcones with sodium hydroxide.

Mechanochemical solid-state synthesis of 2-aminothiazoles, quinoxalines and benzoylbenzofurans from ketones by one-pot sequential acid- and base-mediated reactions
ball-milling conditions – were set up for a sequential base-mediated condensation reaction with thiourea/thiosemicarbazides, o-phenylenediamine and salicylaldehyde to afford 2-aminothiazoles, 2-hydrazinylthiazoles, quinoxalines and benzoylbenzofurans, respectively, in respectable yields. The viability of one-pot sequential acid- and base-mediatedreactions in the solid state under ball-milling conditions
