symmetrical & unsymmetrical polyamine analogues of philanthotoxins has been accomplished using the new Dde based linker. The linker allows the selective attachment of primary amines and the resulting linkage displays excellent stability towards the conditions required for the removal of Fmoc and Boc groups as well as the reductive alkylation conditions used for the elaboration of polyamines. The final cleavage
使用新的基于Dde的接头已成功构建了硫氧还蛋白的对称和不对称多胺类似物。所述连接体允许伯胺的选择性连接,并且所得的连接在去除Fmoc和Boc基团所需的条件以及用于精制多胺的还原性烷基化条件方面显示出优异的稳定性。通过使用挥发性伯胺与连接子的再生进行氨基转移,可以容易地实现多胺或其衍生物从固体载体的最终裂解。
