Enantioselective [3+2] cycloaddition and rearrangement of thiazolium salts to synthesize thiazole and 1,4-thiazine derivatives
Highly efficient asymmetric [3 + 2] cycloaddition reactions of thiazolium salts with a variety of electron-deficient 2- components were achieved by chiral N,N-dioxide/metal complex catalysts, providing a convenient route to access enantioenriched hydropyrrolo-thiazoles. The oxathiazine and sulfinate could be readily obtained by the oxidation of the hydropyrrolo-thiazole. Moreover, through ingenious collaboration of chiral catalysts with basic additives, the first cascade cycloaddition/rearrangement reaction with ,-unsaturated -ketoesters was realized, and various pyrrolo-[1,4]thiazine derivatives were afforded in excellent results.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 147118-35-2, you can contact me at any time and look forward to more communication.
