DFT (M06-L) calculations on the transition state for the 1,3-dipolar cycloadditions between substituted vinyl sulfones with sugar azide have been reported in conjunction with new experimental results, and the origin of reversal of regioselectivity has been revealed using a distortion/interaction model. This study provides the scientific justification for combining organic azides with two different
结合新的实验结果,已报道了取代乙烯基砜与叠氮化物之间的1,3-偶极环加成的过渡态的DFT(M06-L)计算,并且使用失真/互动模型。这项研究提供了将有机叠氮化物与两种不同类型的乙烯基砜结合用于在无金属条件下制备1,5-二取代的1,2,3-三唑和1,4-二取代的三唑基酯的科学依据。
