- A new synthetic entry to (-)-lasubineI and (+)-subcosineI has been established by employing the (S)-allylalkoxy benzylamine as a chiral synthon. The synthesis involves the formation of an α,β-unsaturated lactone by RCM reaction followed by an intramolecular Michael-type addition reaction as a key step, which enables the stereoselective construction of the cis-quinolizidine skeleton of lasubine
- 通过使用 (S)-烯丙基烷氧基苄胺作为手性合成子,建立了 (-)-lasubine I 和 (+)-subcosine I 的新合成条目。该合成涉及通过RCM反应形成α,β-不饱和内酯,然后是分子内迈克尔型加成反应作为关键步骤,这使得能够立体选择性地构建lasubine I和subcosine I的顺式-喹啉酮骨架。
