A short synthesis of the 5-HT3 receptor antagonist RS-42358 was developed based on the condensation of lactone 2 with S3-aminoquinuclidine. The position 2 analogs of RS-42358 were made by condensing various primary amines with lactone 2. The key step in the synthesis of lactone 2 was lateral lithiation of diethyl amide 7 using n-BuLi in THF.
基于内酯 2 与 S3-氨基奎宁环的缩合,开发了 5-HT3 受体拮抗剂 RS-42358 的简短合成。 RS-42358 的 2 位类似物是通过各种伯胺与内酯 2 缩合制备的。合成内酯 2 的关键步骤是使用正丁基锂在 THF 中对二乙酰胺 7 进行侧向锂化。
