PdCl2-catalyzed hydrosulfonamidation of homo allylic alcohols: an efficient synthesis of allylic sulfonamides

A new protocol for the palladium chloride-catalyzed direct hydrosulfonamidation of homoallylic alcohols with migration of the double bond is described. This method requires no preactivation of alcohols and the reaction is environmentally benign with water as the only by-product. Various homoallylic alcohols on hydrosulfonamidation with sulfonamides gave the corresponding products in good yields.
