中文摘要：

以对氯苯磺酰胺为氮源,Ph I（OAc）_2为氧化剂,Cu（CF_3SO_3）_2为催化剂,β-双羰基衍生物为底物,于35℃用＂一锅法＂合成了6个α-氨基-β-双羰基化合物（3a~3f,3b~3f为新化合物）,其结构经^1H NMR,^（13）C NMR和HR-ESI-MS表征。

英文摘要：

Six α-amino-β-dicarbonyl compounds（ 3a ~ 3f,3b ~ 3f were novel compounds） were synthesized by ＂one-pot method ＂ at 35 ℃, using chlorobenzene sulfonamide as nitrogen source,Ph I（ OAc）_2as oxidizing agent,Cu（ CF_3SO_3）_2as catalyst and β-dicarbonyl compounds as substrate.The structures were characterized by~1 H NMR,~（13）C NMR and HR-ESI-MS.
