在二叔丁基二硫醚和相关化合物以及烯酮-S,S-缩醛与原位生成的手性二环氧乙烷的催化单氧化中,发现对映选择性高达75%。溶剂对映体过量的影响也已被检查。(© Wiley-VCH Verlag GmbH & Co. KGaA,69451魏因海姆,德国,2005)
Enantioselectivities up to 75 % have been found in the catalytic mono-oxidation of di-tert-butyl disulfide and related compounds as well as of ketene-S,S-acetals with an in situ generated chiral dioxirane. The effect of solvents on the enantiomeric excess has also been examined. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
