We have succeeded in developing direct syntheses of trans β-azidohydrins and trans 1,2-diol derivatives from olefins catalyzed by dichlorotin oxide. The regioselectivity of these reactions with tri-substituted olefins is high (10:1 in the synthesis of 1,2-diol derivatives) to excellent (>99:1 in the synthesis of azidohydrins). It has been found that these reactions do not proceed via epoxides.
我们已经成功地开发了由二氯氧化锡催化的烯烃直接合成反式β-叠氮醇和反式1,2-二醇衍生物。这些与三取代的烯烃的反应的区域选择性高(在合成1,2-二醇衍生物中为10:1)至优异的(在叠氮醇中合成为> 99:1)。已经发现这些反应不会通过环氧化物进行。
