Triflic acid promoted solvent free synthesis of densely functionalized furans

摘要

A simple, efficient and novel methodology has been developed for the synthesis of densely substituted furans mediated by triflic acid. The current protocol proceeds in a domino fashion, the initial step involves Friedel–Crafts arylation, followed by dehydrative cyclization. It is operationally simple and can be carried out under solvent free conditions.
