In this study, we have successfully applied a visible-light-promoted desulfurization method to the synthesis of deoxysugars, especially 1-deoxyglycose, 2,4-deoxyglycosides, and 2-deoxyglycosides with exclusive α-configuration. Compared to the reported desulfurization under UV light (500 W mercury lamp), this desulfurization under visible light (20 W blue LED) is easy to operate since it does not require a dedicated photochemical reactor, occurs under very mild conditions, and is able to avoid many of the side reactions that often occur during the UV-induced desulfurization.
