In this account we detail the asymmetric synthesis of 1, a potent azepanone-based inhibitor of cathepsin K (Ki = 0.16 nM), which has been shown to inhibit the production of biomarkers of bone resorption in monkeys. The key steps in the synthesis sequence were the utility of the Evans aldol reaction coupled with the ring closing olefin metatheses to assemble the azepanone core contained within 1.
因此,我们详细介绍了1的不对称合成,一种有效的基于氮杂环庚烷的组织蛋白酶K抑制剂(K i = 0.16 nM),已证明它可以抑制猴子骨骼吸收的生物标志物的产生。合成过程中的关键步骤是利用Evans aldol反应与闭环烯烃复分解反应来组装包含在1中的氮杂环庚烷核心。
