It's all in the CAN: Cerium ammonium nitrate (CAN) promotes the oxidative radical cyclization of furan β‐ketoesters to form macrocycles of varying ring sizes. The reaction is tolerant of unsaturation, oxygenation, and nitrogen and oxygen heterocycles in the carbon backbone tether.
一切尽在 CAN 中:硝酸铈铵 (CAN) 促进呋喃 β-酮酯的氧化自由基环化,形成不同环大小的大环。该反应耐受碳骨架系链中的不饱和、氧化以及氮和氧杂环。
