Abstract

A direct PdBr2 (BINAP)-complex catalyzed method has been developed to produce 2, 3- disubstituted indoles by the reaction of arylamines with α-diketones under reductive (H2) conditions. The synthetic methodology involves a tandem reaction of three steps and all the organic intermediates were isolated and characterized, the reduction products in this sequence are chiral and present interesting enantiomeric excess. This report constitutes a ...
