Abstract

Abstract A new and straightforward carbocupration/zinc homologation/β-elimination reaction sequence allows the one-pot synthesis of polysubstituted allenes from acetylenic sulfoxides in excellent isolated chemical yields. Secondary zinc carbenoids were used for the homologation reaction, and so a new synthesis of 1, 1-diiodoalkanes is described. This methodology also allows the synthesis of chiral allenes through thermodynamic ...
