Herein, we describe enantioselective addition of alkenyltin reagents possessing a reactive and sensitive allylic functionality not readilyavailable to other classes of alkenyl metals. This method is enabled by the use of highlyelectrophilic alkylidene Meldrum’s acids as acceptors and a cationic Rh(I)−diene complex as catalyst.
