An efficient approach to unsymmetrical halogenated resorcinol diethers has been developed. This synthesis consists of two subsequent nucleophilic aromatic substitutions (SNAr) of unsymmetrical difluoroarenes by alkoxides. The novelty of this ap
Cyclization of o-(3-hydroxy-3-methylbutynyl)-phenols with boron tribromide to 4-bromo-2,2-dimethylchromenes and their electroreduction to 2,2-dimethylchromenes

Cyclization of o-(3-hydroxy-3-methylbutynyl)phenols (2) with boron tribromide gave easily 4-bromo-2,2-dimethylchromenes (3). Electrolytic reduction of 3 at a Hg-pool electrode afforded the corresponding 2,2-dimethylchromenes (6) in high yields.
