Abstract: Herein, a new approach for the synthesis of 3,3′-biindolin-2-ones is reported. The transformation has been successfully performed following a one-step strategy starting from 3-hydroxy-3-indolyloxindoles. The reaction proceeds smoothly under mild conditions and is applicable to… read more here.
