  • Oxindole dimers have been used as intermediates in the synthesis of various cyclotryptamine alkaloids. An efficient direct synthesis of oxindole dimers has been carried out from 3-substituted oxindoles via an oxidative dimerization using manganese(III) acetate or copper acetate/silver acetate system.
