An approach to the synthesis of sulfonamides from sulfamoyl inner salts and organometallic species is presented. A range of sulfamoyl carbamates, amines, and metals are explored. Primary, secondary, and tertiary alkyl-, aryl-, and heteroaryllitihium and magnesium nucleophiles were successful. This approach yields bench-stable intermediates and avoids many of the functional group incompatibilities,
提出了一种从氨磺酰基内盐和有机金属物质合成磺酰胺的方法。探索了一系列氨磺酰基氨基甲酸酯,胺和金属。伯,仲和叔烷基,芳基和杂芳基和镁亲核试剂是成功的。此方法可产生稳定的中间体,并避免了通常与磺酰胺合成相关的许多官能团不相容性,区域选择性问题和高能试剂。另外,可以通过碱性提取或形成盐来纯化产物,而无需色谱法。
