A novel palladium(0)‐catalyzed intermolecular coupling reaction of 2‐gem‐dibromovinylanilines and N‐tosylhydrazones was reported to construct 2‐(1‐phenylvinyl)‐indoles efficiently. The indole bearing 1, 1‐disubstituted alkenes were obtained in one step with short reaction time, in high yields and broad substrate scope. The formed indole derivates could be easily transformed into much more valuable
Iodine catalyzed C (sp(3))-H functionalization of tosylhydrazones with beta-enamino esters under visible light irradiation for the synthesis of trisubstituted pyrroles has been described. The present method is also applicable to a alpha-substituted tosylhydrazones to yield the tetra-substituted pyrroles.
