Revisiting the Addition of In‐situ Nucleophiles to Allenic Ketones: an Entry Towards Synthesis of Benzodioxins

The manuscript delineates a revisit towards regioselective addition of in situ generated negative nucleophiles to allenic ketones in the presence of a base. A wide variety of allenic ketones as well as nucleophiles are viable in this transformation. A direct ring annulation towards the challenging benzodioxin skeleton synthesis has been developed. Environmentally benign protocol and wide substrate scope are the notable features of this methodology.
