Zinc-mediated chain extension reaction of o-phenolic-l,3-diketone to o-phenolic-l,4-diketone

Liu, Hui-Fang,Meng, Ling-Guo,Hao, Xiao-Li,Qiao-Lin,Li, Jian-Fa,Xue, Song

, p. 216 - 222 (2013/07/26)

A simple methodology has been developed for the synthesis of o-phenolic-l,4-diketones from the o-phenolicl, 3-diketones. The reaction performed in the presence of organozinc reagents under mild conditions afforded the products l,4-diketones in moderate yields.
