title: Total synthesis of (+/-)-perophoramidine.
abstract: The first total synthesis of racemic perophoramidine is described. The key step features the highly stereoselective introduction of the vicinial quaternary centers via base-promoted carbon-carbon bond formation between a 3-alkylindole and a 3-bromo-3-alkylindolin-2-one. This transformation presumably proceeds through a conjugate addition or Diels-Alder cycloaddition of the 3-alkylindole with a 3-alkylindol-2-one intermediate.
