Photoinduced Direct Carbamoylation of Ethers with Isocyanates towards synthesis of α- Amide Substituted Ether Derivatives

Photoinduced carbamoylation of ethers using isocyanates as amide sources was accomplished under mild and environmentally friendly reaction conditions. A series of isocyanates were tolerated in this protocol to construct α-amide substituted ether derivatives with desired yields. The method featured broad substrate scope and good functional group tolerance, which could play an important role in the construction of biological molecules with ethers.
