利用不对称交叉偶联反应合成S-(+)-萘普生

Synthesis of (S)-(+)-Naproxen via asymmetric cross-coupling reaction

用 β -氨基烷基膦的NiCl2 配合物为手性催化剂 ,以 6 -甲氧基 - 2 -溴萘和α -溴代丙酸酯的有机锌试剂为原料 ,通过不对称交叉偶联反应合成S - (+ ) -萘普生。

S)-Naproxen was obtained by asymmetric cross-coupling reaction of 2-bromo- 6-methoxynaphthalene with organozinc reagent of ethyl α- bromopropionate, catalyzed by chiral β-aminoalkylphosphine-nickel complexes.
