Carbohydrates are natural, renewable, chemical compounds that play crucial roles in biological systems. Thus, efficient and stereoselective glycosylation is an urgent task for the preparation of pure structurally well-defined carbohydrates. Photoredox catalysis has emerged as a powerful tool carbohydrate chemistry, providing alternative addressing some challenges glycochemistry. Over last few decades, Ir- Ru-based organometallic photocatalysts have attracted significant interest because their high stability, high-energy triplet state, strong visible-light absorption, long luminescence lifetime, amenability to ligand modification. This review highlights recent progress photocatalyst-promoted synthesis modification carbohydrates under photoirradiation, well related benefits drawbacks.
