Pyrenolide C has been synthesized for the first time using an oxazole template to construct the framework of the ten-membered unsaturated lactone system. The stereochemical assignment of the allylic alcohol substituent, based on the mode of synthesis, has been confirmed by NMR studies.
使用恶唑模板首次合成了吡喃内酯C,以构建十元不饱和内酯体系的框架。基于合成方式的烯丙基醇取代基的立体化学分配已经通过NMR研究得到证实。
