We report the synthesis of a structurally diverse library of chiral Nβ-substituted 1,2-diazetidin-3-ones by a 4-center 3-component Ugireaction comprising unprotected α-hydrazino acids. Various isocyanides and carbonyl compounds and both aldehydes and ketones were utilized. In addition, postcondensation modifications at three different sites have been demonstrated.
我们报告了通过包含未受保护的 α-肼酸的 4 中心 3-组分 Ugi 反应合成结构多样的手性 N β -取代的 1,2-diazetidin-3-ones 文库。使用了各种异氰化物和羰基化合物以及醛和酮。此外,已经证明了三个不同位置的后缩合修饰。
