Technical Notes: 1.Friedel-Crafts Alkylation: Chiral phosphoric acid catalyzed F riedel-Crafts alkylation of indoles with 3,3,3- trifluoropyruvate gave the corresponding adducts in excellent yields with high enantioselectivities. 2.Pinacol Rearrangement: It has been found that indolyl diols can be treated with chiral phosphoric acids to effect a regio- and enantiose lective pinacol rearrangement with high efficiency.
