(11bR)-8,9,10,11,12,13,14,15-Octahydro-4-hydroxy-2,6-di-1-naphthalenyl-4-oxide-dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin, 95%, (98.5% ee)

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.
