A 12-step totalsynthesis of (±)-duocarmycin SA (1) was achieved from a readily available pyrrole 3 by way of 7,10/11,14 and 18, using a SnCl2-mediated reaction of a singlet oxygen adduct 6 with 5, as well as the Heck and Mitsunobu reactions on 9 and 16 as key steps.
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。
