[structure: see text] Crambescidin 359 (4), which is the "vessel part" of the pentacyclic guanidine alkaloid ptilomycalin A (1), was synthesized for the first time based upon successive 1,3-dipolar cycloaddition reaction. This synthesis established the absolute stereochemistry of 4.
[结构:见正文]基于连续的1,3-偶极环加成反应,首次合成了Crambescidin 359(4),它是五环胍生物碱枯草菌素A(1)的“血管部分”。该合成建立了4的绝对立体化学。
