Abstract

A three component one-pot synthesis of 3-substituted indole derivatives by a coupling reaction between indole, aldehydes and amines catalyzed by methane sulphonic acid, under ambient conditions to afford 3-substituted indole in excellent yields, with short reaction time, simple procedure, easy work-up and ecofriendly reaction condition.
