Synthesis of Duocarmycin SA by Way of Methyl 4-(Methoxycarbonyl)oxy-3H-pyrrolo[3,2-f] quinoline-2-carboxylate as a Tricyclic Heteroaromatic Intermediate.
Synthesis of Duocarmycin SA by Way of Methyl 4-(Methoxycarbonyl)oxy-3H-pyrrolo[3,2-f] quinoline-2-carboxylate as a Tricyclic Heteroaromatic Intermediate.
Alternative synthesis of duocarmycin SA (1) was achieved by developing a novel preparation method using palladium catalysts for a tricyclic heteroaromatic compound 4b, followed by transformation into the previously reported intermediates 13 and 14a by way of the alcohol 10b.
通过开发一种新型制备方法,使用钯催化剂制备三环杂芳香族化合物 4b,然后通过醇 10b 转化为之前报道过的中间体 13 和 14a,实现了双胭脂虫酰胺 SA (1) 的替代合成。
