磺酰胺(R 1 R 2 N-SO 2 -NR 3 R 4)通常是使用强亲电试剂和有害试剂(例如N-氨磺酰氯,磺酰氯,三氯氧化磷或五氯化磷)制备的。我们在此报告了一种更安全,更方便的合成方法,该方法可使用N-取代的恶唑烷-2-酮衍生物5作为腐蚀性和有害的N-氨磺酰氯的合成等效物,大规模制备磺酰胺。探索了使用N-氨磺酰基恶唑烷酮制备非对称磺酰胺的范围。
The synthesis of a new series of N-substituted perhydro-1,3-oxazin-2ones containing N-phenylsulfonamide is described. The compounds 7a-7f were obtained in a one-pot reaction from chlorosulfonyl isocyanate, selected 1,3-halogenoalcohols and various aromatic amines in alkaline conditions, to give the target N-heterocyclic 6-membered ring compounds with good yields. The X-ray crystal structure of N-[(N-4-fluorophenyl)sulfamoyl]perhydro-1,3-oxazin-2-one 7d was solved. All the synthesized compounds have been screened for their in-vitro antibacterial activity against Staphylococcus aureus, Eseherichia coli and Pseudomonas aeruginosa. Structures of 7d and 6e can be further optimized to give new potent antibacterial agents with structures significantly different from those of existing classes of antibiotics.
