The ability to reversibly cross‐link proteins and peptides grants the aminoacid cysteine its unique role in nature as well as in peptide chemistry. We report a novel class of S‐alkylsulfonyl‐l‐cysteines and N‐carboxyanhydrides (NCA) thereof for peptide synthesis. The S‐alkylsulfonyl group is stable against amines and thus enables its use under Fmoc chemistry conditions and the controlled polymerization

The amidederivedfrom 4-hydroxy-l-proline and 2,6-dimethylaniline is a powerful ligand for Cu-catalyzed coupling of (hetero)aryl halides with sulfinic acidsalts, allowing the formation of a wide range of (hetero)aryl sulfones from the corresponding (hetero)aryl halides at considerably low catalytic loadings. The coupling of (hetero)aryl iodides and sodium methanesulfinate proceeds at room temperature

sodium sulfinates, which provides a series of α-trifluoromethyl-β-sulfonyl tertiary alcohols. This new synthetic protocol is enabled by a charge-transfer complex between oxygen and sulfinates, featuring broad substrate scope and scalability. Excellent functional group compatibility and chemoselectivity render this method suitable for sulfonation of pharmaceutically relevant molecules. In the presence
本文报道了 α-三氟甲基苯乙烯与亚磺酸钠的可见光诱导磺化,其提供了一系列 α-三氟甲基-β-磺酰基叔醇。这种新的合成方案由氧和亚磺酸盐之间的电荷转移复合物实现,具有广泛的底物范围和可扩展性。优异的官能团兼容性和化学选择性使该方法适用于药学相关分子的磺化。在 D 2 O存在下,还获得了氘代三氟化产物,进一步证明了该策略的灵活性和合成潜力。
