α-Aminomethyl tetrazoles, recently made accessible by an Ugi multicomponent reaction (MCR), were shown to be excellent starting materials for a further Ugi MCR, yielding substituted N-methyl-2-(((1-methyl-1H-tetrazol-5-yl)methyl)amino)acetamides having four points of diversity in a library-to-library approach. The scope and limitations of the two-step sequence was explored by conducting more than 50 reactions. Irrespective of electron-rich and electron-deficient oxo-components and the nature of the isocyanide component, the reactions give excellent yields. Sterically less hindered α-aminomethyl tetrazoles give better yields of in further Ugi MCR. The target scaffold has four points of diversity and is finding applications to fill screening decks for high-throughput screening (HTS) in the European Lead Factory and in structure-based drug design.
α-氨甲基四唑最近通过 Ugi 多组分反应（MCR）变得易于获得，被证明是进一步 Ugi MCR 的极好起始原料，通过库对库方法产生了具有四个多样性点的取代的 N-甲基-2-(((1-甲基-1H-四唑-5-基)甲基)氨基)乙酰胺。通过进行 50 多次反应探索了两步序列的范围和限制。无论富电子和缺电子的氧组分以及异氰化物组分的性质如何，反应都能获得优异的产率。空间位阻较小的α-氨甲基四唑在进一步的 Ugi MCR 中能获得更好的产率。目标支架具有四个多样性点，正在被用于填补欧洲先导工厂高通量筛选（HTS）和基于结构的药物设计中的筛选库。
