We report a minimalist gaseous sulfonyl-chloride-derived reagent for multicomponent bioconjugation with amine, phenol, or aniline reagents to afford urea or carbamate products. With the utilization of a gas-phase reagent for a reaction mediated by metal ions, a variety of biologically relevant molecules, such as saccharide, poly(ethylene glycol), fluorophore, and affinity tag, can be efficiently cross-linked to the N terminus or lysine side-chain amines on natural polypeptides or proteins.
我们报道了一种极简的气态磺酰氯衍生试剂，可与胺、酚或苯胺试剂进行多组分生物偶联，生成脲或氨基甲酸酯产物。通过利用气相试剂进行金属离子介导的反应，可以有效地将各种生物相关分子，如糖、聚乙二醇、荧光团和亲和标签，交联到天然多肽或蛋白质的 N 末端或赖氨酸侧链氨基上。
