  A copper‐catalysed (diacetoxyiodo)benzene‐promoted aerobic esterification reaction of acetoacetamides was developed for the synthesis of oxamates, which are useful precursors in synthetic organic chemistry. This practical and mild synthetic approach proceeded at 25 °C under open‐air conditions and afforded methyl 2‐oxo‐2‐(phenylamino)acetates in good to excellent yields combined with C−C σ‐bond cleavage

  作者：Jing-Yu He、Xiu-Qing Song、Hong Yan、Ru-Gang Zhong

  DOI：10.1002/jhet.989

  日期：2012.11

  The 4‐aryl‐1,4‐dihydropyrazines were prepared via the cyclization of N,N‐bisalkylated anilines with ammonium acetate. These reactions were aided by improvements in the synthesis of N,N‐bisalkylated anilines which were alkylated with anilines using ethyl 2‐diazo acetoacetate in a reaction catalyzed by rhodium acetate in the absence of oxygen. A possible mechanistic route is postulated on the basis of
