Mesoporous Al-MCM-41 catalyzes the chemoselective Michael addition reaction between indoles and α,β-unsaturated ketones to afford β-indolylketones at room temperature with excellent yields. The higher catalytic activity is attributed to Lewis acidic Al and the large surface area. The catalyst is readily recovered and reused more than six times without loss in its catalytic activity. The substitution at the indole nucleus occurs exclusively at the 3-position and N-alkylation products are not observed.
Poly(N,N'-dibromo-N-ethyl-benzene-1,3-disulfonamide), N,N,N',N'- tetrabromobenzene-1,3-disulfonamide as new reagents for conjugate addition of indole, pyrrole with a,b-unsaturated ketones

experimental part, p. 1406 - 1410 (2009/04/04)
Asymmetric Michael-type Friedel-Crafts (F-C) alkylations of indoles with nonchelating α,β-unsaturated aromatic ketones catalyzed by a chiral H8-BINOL-based phosphoric acid were investigated. The reactions took place smoothly in the presence of
