Efficient Synthesis of Bis(indolyl)methane Derivatives on Heterogeneous Ga‐MCM‐41‐SO 3 H Catalyst under Mild Conditions
Year: 2024
Type: article
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 and aldehydes in a one‐pot procedure using Ga‐MCM‐41‐SO 3 H heterogeneous catalyst. Notably, the use of this catalyst has resulted in high yield of products (up to 98 %) under mild conditions, and the catalyst was found to be stable and reusable, retaining its highly catalytic activity even after five runs. Interestingly, two alkaloids Arsindoline A and Turbomycine B were successfully synthesized in the employment of this catalyst. These findings suggest that Ga‐MCM‐41‐SO 3 H could be a promising alternative to traditional acid homogeneous catalysts in the synthesis of bis(indolyl)methane derivatives, offering several advantages including ease of separation and reuse, high stability, and low toxicity.
