A novel synthesis of 4-dioxy-2-enones from 1,3-dienes using pyridinium dichromate–tret-butyl hydroperoxide
Abstract
Treatment of 1,3-dienes with the pyridinium dichromate (PDC)–ButOOH reagent system leads directly to the formation of 4-tret-butyldioxy-2-enones in good yield under mild reaction conditions.
