The synthesis of bis(indolyl)methane derivatives in the reaction between indoles and aldehydes was carried out in a short reaction time (10-20 minutes) with good yield (78-96%) by using 1 mol% of nanoγ-Al2O3in H2O as a green solvent at room temperature. Moreover, we usednanoγ-Al2O3 as an effortlessly accessible, less costly, and possible under eco-friendly conditions catalyst […]
