A CuBr-mediated, regioselective cross-coupling between methyl 2,5-diiodobenzoate (4) and [(diethoxyphosphinyl)difluoromethyl]zinc bromide is reported. Palladium-catalyzed incorporation of an amino acid side chain, followed by subsequent modifications resulted in the rapid construction of 2. Compound 2 was designed to engage Cys188 of the Src SH2 domain, however, this was not observed spectroscopically
据报道,在
2,5-二碘苯甲酸甲酯(4)与[(二乙氧基膦基)二
氟甲基]
溴化锌之间存在CuBr介导的区域选择性交叉偶联。
钯催化的
氨基酸侧链的掺入,随后进行的修饰导致2的快速构建。将化合物2设计为与Src SH2域的Cys188结合,但是,在光谱上没有观察到。
