The synthesis of cis-β-amidevinyl benziodoxolones from the ethynyl benziodoxolone–chloroform complex and sulfonamides is reported. Evidence indicates that highly reactive unsubstituted ethynyl benziodoxolone undergoes Michael addition of sulfonamides, including sterically demanding acyclic amino acid derivatives. The synthesis of selectively deuterated cis-β-amidevinyl benziodoxolones and investigation
据报道,由乙炔基苯并恶唑啉酮-氯仿配合物和磺酰胺合成了顺式-β-酰胺基乙烯基苯并恶唑啉酮。有证据表明,高反应性未取代的乙炔基苯并恶唑啉酮会经历迈克尔加成反应,包括空间上需要的无环氨基酸衍生物。选择性地氘化的合成顺式-β-amidevinyl benziodoxolones和乙炔基λ的调查3 -iodane反应性也进行了描述。
