Abstract

Abstract: A naturally biodegradable, reusable, and eco-safe catalyst, i.e., uric acid was developed and exploited for the green, facile and economical one-pot synthesis of pyran annulated heterocyclic systems from starting materials. This method gives an insight into the credibility of pathway followed by the aforementioned green and reusable catalyst in aiding the heterocyclic compounds formation. High atom economy, cleaner reaction profile, simple column-free work up condition, shorter reaction times, high to excellent yields, eco-safe and high catalytic activity make this present procedure an interesting alternative to the multistep approaches.
