Abstract

A novel application of solid acid catalysts in the chemoselective Friedel-Crafts (FC) alkylation of indoles is reported. The optimal protocol allows highly functionalized indolyl compds. to be synthesized in excellent yields through conjugate addn. of indoles with a,b-unsatd. ketones and nitro compds. Finally, the use of com. Amberlyst-15 as the heterogeneous catalyst for highly atom efficient continuous and semicontinuous Friedel-Crafts processes is described.
