A direct method for the transformation of α-amino acids into β-amino aldehydes was developed, and applied to the modification of the C-terminal residue of peptides. The method takes place in good yields and under mild conditions. The application of this methodology to the preparation of small peptides with γ-amino alcohol units, which are precursors of analogues of peptaibol antibiotics, is also described.
开发了一种将α-氨基酸转化为β-氨基醛的直接方法,并应用于肽的C末端残基的修饰。该方法在温和条件下进行,产率良好。同时还描述了该方法在制备含有γ-氨基醇单元的小肽方面的应用,这些单元是肽类抗生素类似物的前体。
