An efficient method for the iodine-catalyzed oxidation of N-substituted indoles by using chloramine-B under mild reaction conditions was explored. This reaction was found to be tolerant to a variety of functional groups and provided the corresponding isatins in moderate to excellent yields. In addition, application of this method to the one-pot synthesis of 3-hydroxyoxindole and N-methylisatin oxime
Catalytic enantioselective C–H functionalization of indoles with α-diazopropionates using chiral dirhodium(II) carboxylates: asymmetric synthesis of the (+)-α-methyl-3-indolylacetic acid fragment of acremoauxin A
first catalyticasymmetricsynthesis of the (+)-α-methyl-3-indolylacetic acid fragment of acremoauxin A, a potent plant-growth inhibitor. Furthermore, the Fujioka protocol using a combination of TMSOTf and 2,2′-bipyridyl was shown to be superior for the removal of the N-MOM group.
