Deep eutectic solvents with ultrasonic energy as an environmentally benign and green approach for the synthesis of bisthioglycolic acid derivatives

Abstract

The present methodology explored the effectiveness and versatility of deep eutectic solvent with ultrasonic energy as an eco-friendly protocol for the synthesis of bisthioglycolic acid derivatives. Bisthioglycolic moiety holds its role as a potent scaffold in sulfur-containing drugs. The presented strategy offers significant advantages such as green catalyst as well as solvent, excellent yield, short reaction time, and simple reaction workup. This methodology shows a wide range of substrate scope that contain both electron-donating as well as electron-withdrawing groups. � 2023 Informa UK Limited, trading as Taylor & Francis Group.
