Recent Advances in Organic Photocatalyst‐Promoted Carbohydrate Synthesis and Modification under Light Irradiation

Abstract Photoredox catalysis has been developed as a sustainable and eco‐friendly catalytic strategy, which might provide innovative solutions to solve the current synthetic challenges and barriers in carbohydrate chemistry. During the last few decades, the study of organic photocatalyst‐promoted carbohydrate synthesis and modification has received significant attention, which provides an excellent and inexpensive metal‐free alternative to photoredox catalysis as well as introduces a new fastest‐growing era to access complex carbohydrates simply. In this review, we aim to provide an overview of organic photocatalyst‐promoted carbohydrate synthesis and modification under light irradiation, which is expected to provide new directions for further investigation.
