The catalytic asymmetric synthesis of α,α-difluoromethylated tertiary alcohols is described, using an asymmetric dihydroxylation reaction. This protocol using either the AD-mix-α or AD-mix-β allowed an easy access to these valuable fluorinated chiral building blocks, which have been obtained with excellent yields and er. In addition, the reaction was extended to the α-fluoromethylated analogues.
描述了使用不对称二羟基化反应的催化不对称合成α,α-二氟甲基化叔醇。使用AD-mix-α或AD-mix-β的该方案可以轻松获得这些有价值的氟化手性构件,这些手性已获得了极高的收率和错误率。另外,反应扩展至α-氟甲基化的类似物。
