Abstract

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.

Keywords: o-Phenolic-l, 3-diketones, organozinc reagents, trifluoroacetic acid, diiodomethane, chain extension reaction, ophenolic- l, 4-diketones.
