(±)-oxocrinine and (±)-crinine, has been developed. A notable feature in this synthetic route is the construction of tetrahydro-1 H-benzo[c]azepine framework using an intramolecular Heck reaction and the formation of the sterically congested spiro cyclohexenone intermediate with a Robinson annulation.
已经开发了一种灵活的策略,可以合成 crinine 型石蒜科生物碱,(±)-oxocrinine 和 (±)-crinine。该合成路线的一个显着特征是使用分子内 Heck 反应构建四氢-1 H-苯并[c]氮杂环骨架,并形成空间拥挤的螺环己烯酮中间体和罗宾逊环。
