Recent advances in the synthesis of C-Aryl-glycosides since 2019

Abstract

C-Aryl-glycosides represent a significant subclass of crucial glycosidic compounds, increasingly capturing the attention of pharmaceutical developers as bioelectronic motifs embedded within glycosides. Their outstanding resistance to enzymatic hydrolysis bestows a distinctive advantage in the field of drug development, particularly in therapeutic domains such as diabetes treatment, where pharmaceuticals based on the C-Aryl-glycosides architecture manifest compelling therapeutic efficacy. As a result, researchers in the realm of synthetic chemistry have diligently explored and devised a plethora of streamlined and efficacious synthetic methodologies. This comprehensive review systematically delineates methodologies employed in recent years for the efficient synthesis of C-Aryl-glycosides, offering insights into three primary directions: transition metal catalysis, radical strategies, and metal-free catalysis process.
