A new chiral reagent has been developed for generalized installation of pharmacophoric (S)‐ or (R)‐2‐(alkoxyphosphono)‐1‐amino‐2,2‐difluoroethyl group into organic compounds. The original synthetic application of this new reagent is exemplified by Friedel–Crafts reactions with indoles, which proceed efficiently with excellent diastereoselectivity to give enantiomerically pure products.
已开发出一种新的手性试剂,用于将药效团(S)或(R)-2-(烷氧基膦基)-1-
氨基-2,2-二
氟乙基普遍安装到有机化合物中。这种新试剂的原始合成应用以与
吲哚的Friedel-Crafts反应为例,该反应以优异的非对映选择性高效进行,得到对映体纯的产物。
