The number of known pyrrolyzidine alkaloids of the ester type is on the increase (e.g. Leonard1), but their total synthesis, which could finally prove the relative and absolute configuration, has not yet been accomplished. Now we report the first total synthesis of the simplest group of ester alkaloids containing isomeric 1-hydroxymethylpyrrolyzidines as necines, esterified by isomeric 2-isopropyl-2
已知的酯型吡咯烷生物碱的数量正在增加(例如Leonard 1),但是它们的总合成(最终可以证明其相对和绝对构型)尚未实现。现在,我们报道了最简单的一组酯生物碱的首次全合成,该酯生物碱包含异构体1-羟甲基吡咯烷作为烟碱,并被异构体2-异丙基-2,3-二羟基丁酸酯化。已经确定了化合物的相对和绝对构型。
