strategy of one-pot synthesis of protoberberine alkaloid derivatives via palladium-catalyzed cascade α-arylation and cyclization, which can afford the target molecules in moderate to excellent isolated yields using commercially available raw materials under solvent-free conditions. This protocol provides an efficient and convenient path to multisubstituted protoberberine derivatives. In addition, it can
在这项工作中,我们报告了通过钯催化的级联α-芳基化和环化一锅法合成原小檗碱衍生物的策略,该策略可以在无溶剂条件下使用市售原料以中等至优异的分离产率提供目标分子. 该协议为多取代的原小檗碱衍生物提供了一条高效便捷的途径。此外,它可以直接负担天然生物碱。
