Abstract
The benzannulation reactions of substituted 3‐alkoxycarbonyl‐3,5‐hexadienoic and 3‐alkoxycarbonylhex‐3‐en‐5‐ynoic acids offer a straightforward access to various polysubstituted aromatic compounds. The process is very flexible, and can be applied to the regiospecific preparation of oligoaryls, naphthalenes, ring‐fused heterocycles, chiral tetrahydronaphthalenes, C‐aryl‐glycosides and many natural products of different structure. In this Concept article, we highlight the potential of this annulation reaction by illustration of our recent contribution to this field, as well as the studies previous reported by others.
