The first total synthesis of (+)-amabiline, an unsaturated pyrrolizidine alkaloid from Cynoglossum amabile, is reported. This convergent, enantioselective synthesis proceeds in 15 steps (10-step longest linear sequence) in 6.2% overall yield and features novel methodology to construct the unsaturated pyrrolizidine or (−)-supinidine core.
首次全合成了 (+)-amabiline,一种来自Cynoglossum amabile的不饱和吡咯里西啶生物碱。这种收敛的对映选择性合成过程需要 15 个步骤(10 步最长线性序列),总产率为 6.2%,并且具有构建不饱和吡咯里西啶或 (−)-supinidine 核心的新颖方法。
