The synthesis of a novel spiro[1-benzofuran-2,4â²-piperidin]-3-one scaffold 6 has been achieved in five steps with an overall yield of 47%. The versatility of the spiropiperidine scaffold in the context of library synthesis is exemplified by selective and sequential derivatisation of the amino and aryl bromide functional groups, including the development of multi-step telescope reaction matrices.
通过五步反应,总产率为47%,成功合成了新型螺[1-苯并呋喃-2,4′-哌啶]-3-酮骨架6。在库合成背景下,螺哌啶骨架的多功能性通过选择性和顺序衍生化氨基和芳基溴功能团得以体现,包括开发多步缩合反应矩阵。
