Highly Stereoselective Facile Synthesis of 2-Acetoxy-1,3(<i>E</i>)-alkadienes via a Rh(I)-Catalyzed Isomerization of 2,3-Allenyl Carboxylates

Abstract

A highly stereoselective Rh(I)-catalyzed 1,3-acetoxyl rearrangement of 1,2-allen-3-yl carboxylates leading to 2-acetoxy-1,3(E)-alkadienes has been developed. In addition to the high catalytic efficiency and the scope, the excellent E-selectivity of the double bond is remarkable
