DOI: 10.1021/acs.organomet.9b00112
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.8b03337
Abstract: By using a new catalytic system (PdCl2[P( n-Bu)3]2 in combination with ZnEt2), various 3-indolylmethanol derivatives were successfully carboxylated with CO2 (1 atm) via dearomatization of the indole nucleus, affording 3-methyleneindoline-2-carboxylates. In contrast, carboxylation of 2-indolylmethanol… read more here.
