method for the preparation of 2-nitro-4-(trifluoromethyl)benzene containing sulfides from 1,1′-disulfanediylbis[2-nitro-4-(trifluoromethyl)benzene] is proposed. The corresponding enantiomerically enriched sulfoxides with up to 78% enantiomeric excess are prepared by the asymmetric oxidation of sulfides using a modified Sharpless method. The yield of sulfoxides is shown to decrease with an increase in
摘要 提出了一种由1,1'-二硫烷二基双[2-硝基-4-(三氟甲基)苯]制备含硫化物2-硝基-4-(三氟甲基)苯的高效一锅法。相应的对映体富集亚砜具有高达 78% 的对映体过量,通过使用改进的 Sharpless 方法对硫化物进行不对称氧化来制备。显示亚砜的产率随着脂肪族基团体积的增加和烃部分对硫原子的诱导作用的降低而降低。补充材料可用于本文。转至出版商在线版的磷、硫和硅及相关元素,查看免费的补充文件。图形概要
