Cu-Catalyzed Cross-Dehydrogenative Coupling Reactions of (Benzo)thiazoles with Cyclic Ethers
摘要:
Copper-catalyzed cross-dehydrogenative coupling (CDC) reactions of (benzo)thiazoles with cyclic ethers were developed under mild conditions. In particular, the formation of C-C bonds via the CDC reactions between non-benzo-fused azoles and ethers are reported for the first time. In addition, the acetals, known as the masked 2-thiazolecarboxaldehydes, could be successfully obtained by this CDC reaction. The preliminary mechanism and supportive DFT calculations are discussed as well.
Hydroxyalkylated N-heteroaromatics are interesting scaffolds in a wide range of biologically active natural molecules. Herein, a photoredox-catalyzed hydroxyalkylation method for azole derivatives with aldehydes in the aqueous phase under an air atmosphere has been established. Furthermore, our catalytic system is also suitable for the alkylation of azole derivatives with alkanes. This methodology
