9 Friedel–Crafts and related reactions of nucleophilic alkenes The intramolecular Friedel–Crafts acylation is a reliable process for the formation of five-membered carbocycles as part of fused polycyclic architectures. The Friedel–Crafts acylation has been used in two distinct strategies for the synt...
