The highly diastereoselective InCl(3)-catalyzed aza-Friedel-Craftsreaction of substituted indoles with aldimines generated from Kunz's amine was studied. The reaction afforded the desired product in good to high yields with up to >19:1 diastereoselective ratios. The O-pivaloylated beta-D-galactosyl moiety could not be cleaved under the traditional acidic conditions. It was removed successfully after
