succinic acid over a rhodium (I)-chiral phosphine complex. Highly chemoselective amide formation of di-4-nitrophenyl (R)-(1-naphthylmethyl)succinate with morpholine followed by coupling with methyl (S)-histidinate readily produced the title key synthetic intermediate.
光学拆分(R)-(1-萘基甲基)琥珀酸可通过光学拆分和不期望的对映体的外消旋化或通过铑(I)-手性催化不对称还原(1-萘基亚甲基)琥珀酸来有效制备。膦配合物。用吗啉将二-4-硝基苯基(R)-(1-萘基甲基)琥珀酸酯的高度化学选择性酰胺形成,然后与(S)-组氨酸甲酯偶合,很容易制得标题关键的合成中间体。
