A convenient synthesis of Boc-DL-5,5-dimethylproline methyl ester is described. This conformationally-constrained amino acid may be expected to exist predominantly in the cis peptide bond isomer when into peptides. The peptide bond in the model peptide Boc-Phe-Me2Pro-OMe is shown to be 90% in the cis isomer.
描述了Boc-DL-5,5-二甲基脯氨酸甲酯的方便合成。当进入肽时,可以预期该构象受限的氨基酸主要存在于顺式肽键异构体中。模型肽Boc-Phe-Me 2 Pro-OMe中的肽键显示为90%的顺式异构体。
