Published in 2024 at "Frontiers in Chemistry"

DOI: 10.3389/fchem.2024.1460384

Abstract: A novel analogue of hybrid spirooxindoles was synthesized employing a systematic multistep synthetic approach. The synthetic protocol was designed to obtain a series of spirooxindole derivatives incorporating triazolyl-s-triazine framework via [3 + 2] cycloaddition (32CA)… read more here.
