A diversity-oriented synthesis approach to macrocycles via oxidative ring expansion

Abstract: Macrocycles are key structural elements in numerous bioactive small molecules and are attractive targets in the diversity-oriented synthesis of natural product-based libraries. However, efficient and systematic access to diverse collections of macrocycles has proven difficult using classical macrocyclization reactions. To address this problem, we have developed a concise, modular approach to the diversity-oriented synthesis of macrolactones and macrolactams involving oxidative cleavage of a bridging double bon… Show more

“…Gratifyingly, the N-alkylation/HIRE protocol developed for 10a (vide supra) was found to be fully transferrable (Scheme 2) onto the other twelve substrates (10b-m). Surprisingly, N-alkylation with diethyl sulfate required refluxing temperatures, which resulted in generally lower yields of [1, 4,7]oxadiazecin-9(6H)-ones (16n-q). Notably, compounds 16a-q (Fig.…”
