Two new classes of alkaloids, halichlorine and pinnaic acid, were isolated from marine organisms. A tandem cycloaddition and isomerization have accomplished a short and general synthesis of the azaspirocyclic core structure of halichlorine and pinnaic acid.
从海洋生物中分离出两类新的生物碱,盐酸盐和松果酸。串联环加成和异构化已完成了盐酸和品尼酸的氮杂螺环核心结构的简短合成。
