consists of a Wang resin anchored by an amino acid chain including allylglycine. By olefin cross metathesis with vinylglycine, unsaturated protected (2S,6R)-A2pm was fixed on solid support. Peptides were achieved by cleavage of cross metathesis products from resin, followed by reduction of double bonds along removing of protecting groups. Furthermore, this efficient solid phase approach will lead to peptide
在这里,我们描述了一种有效的固体支持方法的开发,该方法用于立体选择性合成两个含有(2 S,6 R)-二氨基庚二酸,(S)-Ala-γ-(R)-Glu-(2 S, 6 R)-A 2 pm-(R)-Ala 1和γ-(R)-Glu-(2 S,6 R)-A 2 pm 2。该平台由Wang树脂组成,该Wang树脂由包含烯丙基甘氨酸的氨基酸链锚定。通过乙烯基甘氨酸与烯烃交叉复分解,得到不饱和保护的(2 S,6 R)-A 2下午固定在坚实的支持。通过从树脂上裂解交叉复分解产物,然后沿着去除保护基团的双键还原来获得肽。此外,这种有效的固相方法将产生肽和多肽文库。
