A convenient and efficient phosphine-catalyzed sequential annulation domino reaction between dienic sulfones and MBH carbonates has been developed. In the presence of 20 mol% of tris(4-fluorophenyl)phosphine, functionalized bicyclo[4.1.0]heptenes were prepared in excellent yields and stereoselectivities under mild conditions.
