title: Highly diastereoselective DABCO-catalyzed [3 + 3]-cycloaddition of 1,4-dithiane-2,5-diol with azomethine imines.
abstract: An effective diastereoselective [3 + 3] cycloaddition of 1,4-dithiane-2,5-diol with azomethine imines catalyzed by DABCO is described. A variety of highly functionalized six-membered dinitrogen-fused heterocycles can be obtained in good yield with excellent diastereoselectivity, which was controlled by anomeric effect.
