Abstract: A Pd-catalyzed dearomative arylvinylation reaction of indoles with N-arylsulfonylhydrazones as coupling partners is developed, which proceeds via a domino sequence involving dearomative carbopalladation, Pd-carbene migratory insertion, and regioselective β-hydride elimination. A range of 3-vinylindolines bearing… read more here.

DOI: 10.1021/acs.orglett.8b00191
Abstract: A new palladium-catalyzed asymmetric addition reaction of indoles to alkoxyallenes is reported. Remarkably, the reaction showed complete regioselectivity toward the nitrogen. A new mechanism distinct from that of conventional π-allyl chemistry is proposed to explain… read more here.

DOI: 10.1246/bcsj.20180098
Abstract: The complex of chiral C2-symmetric bis-1,2,3-triazole and an achiral Bronsted acid is introduced as a new class of chiral acid catalysts. The catalytic activity and stereocontrolling ability of this chiral Bronsted acid can be tuned… read more here.
