A concise method to prepare novel fused heteroaromatic diones through double Friedel–Crafts acylation†
Abstract
This paper explored the intramolecular double Friedel–Crafts acylation strategy in approaching different types of novel fused heteroaromatic diones (12 samples using 2,2′-bithiophene, 2,2′-bifuran, 2,2′-biselenophene, and 2,2′-bipyrrole as cores) with 16%–85% yield.
