C-3 epimeric secondary zinc reagents 2a/b were prepared from either diastereoisomeric iodide 3a or 3b using DMF as solvent, and characterised by 1H NMR methods. Palladium catalysed cross couplings and copper promoted allylations yielded protected β-methyl substituted amino acids.
C-3 立体异构的二级锌试剂 2a/b 是通过使用 DMF 作为溶剂,从非对映体碘化物 3a 或 3b 制备的,并通过 1H NMR 方法进行了表征。钯催化的交叉偶联反应和铜促进的烯丙基化反应获得了保护的 β-甲基取代氨基酸。
