Asymmetric hydrogenation of tetrasubstituted olefins of cyclic β-(arylsulfonamido)acrylates produces the corresponding cyclic β-(arylsulfonamido)propionates using Pd(OCOCF3)2/diphosphine complexes as catalysts in the presence of TFA with up to 96% ee.
环状β-(芳基磺酰胺基)丙烯酸酯的四取代烯烃的不对称氢化反应在PFA(存在高达96%ee)的条件下,使用Pd(OCOCF 3)2 /二膦配合物作为催化剂,生成相应的环状β-(芳基磺酰胺基)丙酸酯。
