The N-Boc indoles can be transformed into indolin-3-ones in acetonitrile, using RuCl3·3H2O as catalyst and sodium periodate (1.5 equiv) as oxidant. Further, a possible mechanism has been proposed on the basis of control experiments. Key words Key words ruthenium - oxidative dearomatization - indoles - indolin-3-ones - sodium periodate Full Text References References 1a Chen I.-S, Chen H.-F, Cheng M.-J, Chang Y.-L, Teng C.-M, Tsutomu I, Chen J.-J, Tsai I.-L.
