A new approach for the synthetically important γ-functionalized enals has been developed. The strategy involves rhodium-catalyzed direct C-C & C-S bond forming site-selective γ-difunctionalization of diazoenals with aryl propargyl sulfides via sulfur ylide [2,3] sigmatropic rearrangement, resulting in highly functionalized γ-allenyl(sulfanyl)enals excellent yield at ambient temperature. This versatile constitutes a viable alternative to remote carbonyl-directed γ-functionalization unmodified which suffer from competitive side reactions. synthetic utility was demonstrated by InCl
