In this article, we describe further studies toward the originally proposed structure of diazonamide A (1). After confronting a number of failures in synthesizing the heterocyclic core of that structure, success was finally realized through the development of a novel hetero-pinacol-based macrocyclization cascade sequence. Subsequent elaboration led to an advanced compound bearing both of the 12-membered
在本文中,我们描述了对最初提出的重氮酰胺 A (1) 结构的进一步研究。在合成该结构的杂环核心时遇到了许多失败后,最终通过开发一种新的基于杂频哪醇的大环化级联序列实现了成功。随后的精心设计导致了一种先进的化合物,该化合物带有目标分子的两个 12 元环。此外,还描述了通过开发的序列获得的中间体和简化类似物的初步生物学研究。
