A New Access to 3-(2'-Aminovinyl)indoles and Their First Diels-Alder Reactions
Pindur, Ulf,Otto, Christian
, p. 403 - 406 (2007/10/02)
3-Acylindoles react with α-amino-α'-diphenylphosphinoyl-substituted carboanions to 3-(2'-aminovinyl)indoles (7 and 12) via carbinols.The electron-rich 3-vinylindoles 7 and 12 undergo Diels-Alder reactions with N-phenylmaleimide.
