An efficient micelle promoted one-pot synthesis of 3-amino alkylated indoles has been developed via a three-component Mannich-type reaction from secondary amines, aldehydes and indoles in water under mild reaction conditions. In this Mannich-type reaction, micelles stabilize iminium ions, which undergo a nucleophilic addition of the indole to give 3-amino alkylated indoles in very good yields.
