A one-pot procedure for the conversion of carboxylic acids to N-acyl sulfonamides, via thio acid/azide amidation, is presented. The method is compatible with acid- and base-sensitive amino acid protection. N-Acyl sulfonamide synthesis on solid support, peptide thio acid/sulfonazide coupling, and N-alkyl amide synthesis via selective cleavage of sulfonyl from an N-alkyl-N-acyl sulfonamide are also reported
提出了一种一锅法,用于通过硫代酸/叠氮化物酰胺化将羧酸转化为N-酰基磺酰胺。该方法与对酸和碱敏感的氨基酸保护兼容。还报道了在固体载体上合成N-酰基磺酰胺,肽硫酸/磺叠氮化物偶联以及通过从N-烷基-N-酰基磺酰胺选择性裂解磺酰基而合成的N-烷基酰胺。
