Iodobenzene diacetate (PIDA)/Zn(II)-mediated oxidation and cleavage of C-C bond: Formation of substituted N-aryl carbamoyl methyl diacetates and derivatives from 3-oxo-butanamides

Wenjun, Hu,Zhaohui, Deng,Chen, Cui,Liu, Wei-Bing

, p. 571 - 572,2 (2020/09/16)

Various substituted N-aryl carbamoyl methyl diacetates have been synthesized from N-aryl-3-oxobutanamides via a diacetoxylation mediated by the combination of iodobenzene diacetate (PIDA)/Zn(OAc)2. This provides a new convenient method to form C-O bonds and cleave C-C bonds. Ten examples were obtained from easily available materials in good to excellent yields.
