Simple, One-Pot, and Facile Synthesis of Angularly Fused [6-7-5], [6-7-6], [6-7-7], and [6,7] Ring Systems Using Baylis-Hillman Acetates

A simple, convenient, and one‐pot synthesis of angularly fused [6‐7‐5], [6‐7‐6], [6‐7‐7], and [6,7] carbocyclic ring systems from Baylis–Hillman acetates through a strategy involving alkylation, formation of a vinyl chloride, and intramolecular cyclization (Friedel–Crafts or Michael reaction) is described.
