Plantazolicin A, a linear decacyclic natural product, exhibits desirable selective activity against the causative agent of anthrax toxicity. The total synthesis of plantazolicin A and itsbiosyntheticprecursorplantazolicinB was successfully achieved by an efficient, unified, and highly convergent route featuring dicyclizations to form 2,4‐concatenated oxazoles and the mild synthesis of thiazoles
Plantazolicin A 是一种线性十环天然产物,对炭疽毒性的病原体表现出理想的选择性活性。通过高效、统一、高度收敛的路线,通过双环化形成2,4-联恶唑以及由天然氨基酸温和合成噻唑,成功实现了植物唑菌素A及其生物合成前体植物唑菌素B的全合成。该报告代表了 Plantazolicin B 的首次合成,并包含了这两种天然产物的首个完整表征数据。

A convergent strategy for the synthesis of truncated analogues of plantazolicin (PZN), a member of the thiazole/oxazole-modifiedmicrocin (TOMM) class of natural products, has been developed. These N-terminal mono-, tri-, and pentazole substructures of PZN were utilized to probe the substrate requirements and thermodynamic ligand binding parameters of an unusually selective PZN methyltransferase (BamL)
