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 a broad scope of substrates. In this process, a number of products were obtained in good to excellent yields (≥99%) using Bronsted acid as a catalyst and benzothiazolines as the hydrogen source.
