A highly efficient enantioselective hydrogenation of α,β-unsaturated nitriles catalyzed by Rh-(R,R)-f-spiroPhos complex has been developed. With Rh-(R,R)-f-spiroPhos catalyst and under mild conditions, a wide range of α,β-unsaturated nitriles including the (E)- and (Z)-isomers of 3-alkyl-3-aryl, 3,3-diaryl, and 3,3-dialkyl α,β-unsaturated nitriles were hydrogenated to the corresponding chiral nitriles
已经开发了一种由 Rh-(R,R)-f-spiroPhos 络合物催化的 α,β-不饱和腈的高效对映选择性氢化。使用 Rh-(R,R)-f-spiroPhos 催化剂,在温和条件下,可生成多种 α,β-不饱和腈,包括 3-烷基-3-芳基的 (E)- 和 (Z)-异构体,3 ,3-二芳基和 3,3-二烷基 α,β-不饱和腈被氢化成相应的手性腈,具有优异的对映选择性(高达 99.9% ee)和高转换数(TON 高达 10,000)。
