experimental part, p. 4103 - 4109 (2011/06/24)
The attachment of phosphonium ion phase tags to chiral binapthyl-based phosphoric acid catalysts, and the use of these materials in a range of organocatalytic asymmetric Friedel-Crafts reactions of indoles has been studied. Placement of the tags at the 3
