seco-duocarmycin SA has been achieved in eleven linear steps from commercially available starting materials. The DSA alkylation subunit can be made in ten linear steps from the same precursor. The route involves C–H activation at the equivalent of the C7 position on indole leading to a borylated intermediate 9 that is stable enough for peptide coupling reactions but can be easily converted to the free
超强抗肿瘤抗生素 seco-duocarmycin SA 的乙酯类似物的合成是由市售起始材料通过十一个线性步骤实现的。 DSA 烷基化亚基可以由相同的前体通过十个线性步骤制备。该路线涉及相当于吲哚上 C7 位置的 C-H 活化,产生硼酸化中间体9 ,该中间体对肽偶联反应足够稳定,但可以轻松转化为游离羟基类似物。
