isocyanides were first developed as a new type of SuFExable synthon, and they are used as building blocks in the Ugireaction (U-4CR). The Ugireaction was established and the substrate scope was investigated, and various sulfonyl fluoro α-amino amides and peptides could be reached in a one-step synthesis. Therefore, this protocol opens a new vision for SuFExable building blocks and click chemistry, and it also
在此,磺酰氟异氰化物首先被开发为一种新型的 SuFExable 合成子,它们被用作 Ugi 反应 (U-4CR) 的构建单元。建立了Ugi反应并考察了底物范围,一步合成可得到各种磺酰氟α-氨基酰胺和多肽。因此,该协议为 SuFExable 构建块和点击化学开辟了新视野,它还提供了一种独特的磺酰氟肽方法。

β-aminoethanesulfonyl chlorides, new building blocks for the synthesis of peptidosulfonamide peptidomimetics, were prepared in a straightforward manner from amino acids. In the crucial synthetic step, sulfonic acids or their sodium salts were converted into the corresponding sulfonyl chlorides using an excess of refluxing thionyl chloride or thionyl chloride/DMF. This simple and effective chlorinating
