Asymmetric aminohydroxylation of various olefins was carried out using bromamine-T as nitrogen source in the presence of (DHQ)2PHAL ligand. The new nitrogen source has been found to be effective in terms of yield and reaction time. The optical purities of the products could be obtained with up to 99% ee.
在(DHQ)2 PHAL配体存在下,使用溴胺-T作为氮源,进行了各种烯烃的不对称氨基羟基化反应。已经发现,新的氮源在产率和反应时间方面是有效的。可以使用高达99%的ee获得产品的光学纯度。
