以市售的4 -溴- 2 -氟- 1,1 ' -联苯为原料,两步合成(S)‐氟比洛芬甲酯。[PdCl2((S)‐羟基‐苯二酚)]催化剂用于完成格氏交叉偶联和高度对映选择性的分子间甲氧羰基化反应。
A highly enantioselective synthesis of (S)‐flurbiprofen methyl ester in two steps from commercially available 4‐bromo‐2‐fluoro‐1,1′‐biphenyl is shown. [PdCl2((S)‐xylyl‐phanephos)] catalyst is used to accomplish both Grignard cross‐coupling and the highly enantioselective intermolecular methoxycarbonylation reaction.
