Published: June 24, 2024

Abstract Indium(III) triflate was found to be an efficient metal catalyst for the electrophilic substitution reaction of substituted indoles with various isatins or aryl aldehydes in acetonitrile solvent afford corresponding 3,3-diaryloxindoles bis(indol-3-yl)methanes, respectively, high yields at room temperature. This new procedure has remarkable features such as experimental simplicity, conversions, good excellent yields, short times, and simple workup procedures

Efficient Synthesis of Bis(indolyl)methane Derivatives on Heterogeneous Ga‐MCM‐41‐SO₃H Catalyst under Mild Conditions

ChemistrySelect, Journal Year: 2024, Volume and Issue: 9(41)

Published: Oct. 28, 2024

Abstract We are reporting a convenient method for the synthesis of bis(indolyl)methane derivatives from relatively cheap and commercially available chemicals such as indoles aldehydes in one‐pot procedure using Ga‐MCM‐41‐SO 3 H heterogeneous catalyst. Notably, use this catalyst has resulted high yield products (up to 98 %) under mild conditions, was found be stable reusable, retaining its highly catalytic activity even after five runs. Interestingly, two alkaloids Arsindoline A Turbomycine B were successfully synthesized employment These findings suggest that could promising alternative traditional acid homogeneous catalysts derivatives, offering several advantages including ease separation reuse, stability, low toxicity.
