A highly efficient asymmetric synthesis of the Akt kinase inhibitor ipatasertib (1) is reported. The bicyclic pyrimidine 2 starting material was prepared via a nitrilase biocatalytic resolution, halogen–metal exchange/anionic cyclization, and a highly diastereoselective biocatalytic ketone reduction as key steps. The route also features a halide activated, Ru-catalyzed asymmetric hydrogenation of a
据报道,Akt激酶抑制剂ipatasertib(1)的高效不对称合成。双环嘧啶2原料是通过腈水解酶生物催化拆分,卤素-金属交换/阴离子环化和高度非对映选择性生物催化酮还原等关键步骤制备的。该路线还具有乙烯基类氨基甲酸酯的卤化物活化,Ru催化的不对称氢化作用,可高产率和对映选择性地生产α-芳基-β-氨基酸3。通过后期酰胺化/去保护/单盐酸盐形成步骤以收敛的方式组装API。
