Total syntheses of lysicamine, (±)-nuciferine, (±)-nornuciferine, (±)-zanthoxyphylline iodide, (±)-O-methylisothebaine, and (±)-trimethoxynoraporphine were accomplished by an approach that involves the formation of aporphine cores through reactions between an isoquinoline derivative and silylaryl triflates promoted by CsF. Unprecedented formations of aporphine cores proceeded in good yields presumably
赖氨酸胺,(±)-核苷,(±)-核苷,(±)-zanthoxyphylline碘化物,(±)-O-甲基异鞘氨醇和(±)-三甲氧基Noraporphine的总合成是通过一种涉及形成甲啡肽核心的方法完成的通过异喹啉衍生物与CsF促进的甲硅烷基芳基三氟甲磺酸酯之间的反应。前所未有的阿啡肽核心形成过程可能是通过[4 + 2]环加成反应以及随后的氢迁移以高收率进行的。
