Synthesis of 3-Substituted 1-Thioacyl- and 1-Thiocarbamoylindoles from alpha-Substituted 2-Isocyanato-beta-methoxystyrenes

[摘要]：3-Aryl-1-thioacylindoles were prepared by treating alpha-aryl-2-isothiocyanato-beta-methoxystyrenes with organolithiums or Grignard reagents, followed by hydriodic acid catalyzed cyclization of the resulting adducts. A one-pot synthesis of 1-thiocarbamoylindoles was achieved by hydriodic acid mediated cyclization of the corresponding thiourea intermediates, prepared from alpha-substituted 2-isothiocyanato-beta-methoxystyrenes and secondary amines.
