A highly efficient diastereoselective transfer hydrogenation of α-aminoalkyl α'-chloromethyl ketones catalyzed by a tethered rhodium complex was developed and successfully utilized in the synthesis of the key intermediates of HIV protease inhibitors. With the current Rh(iii) catalyst system, a series of chiral 3-amino-1-chloro-2-hydroxy-4-phenylbutanes were produced in excellent yields and diastereoselectivities
开发了一种由束缚的铑配合物催化的α-氨基烷基α'-氯甲基酮的高效非对映选择性转移加氢反应,并成功地用于HIV蛋白酶抑制剂关键中间体的合成中。使用当前的Rh(iii)催化剂系统,可以以优异的收率和非对映选择性(最高99%收率,最高99:1 dr)生产一系列手性3-氨基-1-氯-2-羟基-4-苯基丁烷。通过使用Rh(iii)催化剂的两种对映异构体,可以有效地获得所需产物的两种非对映异构体。
