摘要

α-Iodoenones can be efficiently employed as organic electrophiles in the Pd-catalyzed synthesis of 2, 3-disubstituted indoles from 2-alkynyltrifluoroacetanilides. Best results were obtained using the weak ligand As (Ph) 3. The methodology reported provides an efficient entry to indoles bearing a 2-alkenon-2-yl moiety linked in the 3-position, that possesses a scarcely reported substitution pattern.
