Highly enantioselective catalytic asymmetric hydrogenation of α-CF3-enamides has been achieved by employing rhodium–DuanPhos as the catalyst, which provides a readily accessible method for the synthesis of chiral trifluoromethylated amines. The reaction has a broad substrate scope; both aryl- and alkyl-substituted α-CF3-enamides worked smoothly and afford the corresponding chiral amines in high yields
α-CF的高度的对映选择性催化不对称氢化3个-enamides已经通过采用铑DuanPhos作为催化剂,其提供了一种用于手性胺三氟甲基化合成一个易于接近的方法来实现的。该反应具有广泛的底物范围。两个芳基-和烷基-取代的α-CF 3 -enamides顺利工作,并得到高收率和优异的对映选择性的相应的手性胺(高达99%ee)的。
