Rhodium-catalyzed C-H insertion of hydroxylamine-derived sulfamate esters makes possible the synthesis of unique oxathiadiazinane heterocycles, which upon mild reduction furnish differentially substituted 1,2-diamine products. This highly chemo- and diastereoselective transformation underscores the power of catalytic C-H functionalization as a general approach to C-N bond construction.
铑催化的羟胺衍生氨基磺酸酯的C-H插入反应使得独特的氧杂硫二氮杂环烷杂环化合物的合成成为可能,这些杂环化合物经温和还原后可提供不同取代的1,2-二胺产物。这种高度化学选择性和非对映选择性的转化突出了催化C-H官能化作为构建C-N键的通用方法的强大功能。
