A general and efficient method has been developed for the synthesis of 3-aminoalkylated indoles by a three-componentcoupling of indoles, aldehydes, and amines in the presence of a catalytic amount of zwitterionic-type molten salt under solvent-free conditions. The non-hazardous experimental procedure, mild reaction conditions, and the reusability of the catalyst are the notable advantages of the present
PANI-HBF<sub>4</sub>: A Reusable Polymer-Based Solid Acid Catalyst for Three-Component, One-Pot Synthesis of 3-Substituted Amino Methyl Indoles Under Solvent-Free Conditions
Abstract A simple, fast, efficient, high-yielding, and green process is developed for one-pot, three-componentsynthesis of 3-substituted amino methyl indolesundersolvent-freeconditions using polyaniline salt as polymer-based reusable solid acid catalyst at room temperature. The advantages of polyaniline salt catalyst are ease of synthesis and handling, low cost, versatality, and recyclability.

An efficient protocol was developed for the synthesis of 3-aminoalkylated indoles using 3-chlorophenylboronic acid as a catalyst under ambient temperature conditions. The three-component reaction of indoles, aromatic aldehydes and N-methyl aniline offered corresponding 3-aminoalkylated indoles in excellent yields. This protocol presents some remarkable features such as mild reaction conditions, simple workup procedure and excellent yields. (C) 2013 Sudhakar R. Bhusare.
