probe the biomimetic synthesis of the lantibiotics from their precursor peptides. A novel synthetic methodology was developed to allow the synthesis of multiple dehydroamino acid containing peptides. Cyclisations were rapid, quantitative and regiospecific. Remarkably the peptide sequences alone appear to contain sufficient information to direct a series of stereo- and regiospecific ring closures. Thus
羊毛硫抗生素是一类高度翻译后修饰的小肽抗生素,含有大量羊毛硫氨酸和脱氢氨基酸残基。我们已经制备了包含多个脱氢氨基酸和半胱氨酸残基的肽,以探测羊毛硫抗生素从其前体肽的仿生合成。开发了一种新颖的合成方法,以允许合成多个含脱氢氨基酸的肽。环化反应快速,定量且具有区域特异性。值得注意的是,单独的肽序列似乎包含足以指导一系列立体和区域特异性环闭合的信息。因此,用于B环和E环的两个线性肽都立体选择性地闭合。对于含有两个脱氢氨基酸的A环前体肽,
