Transition-Metal-Free Unusual Oxidative Cleavage of Homoallylic Alcohol and Its Application in the Upcycling of Terpene to Value-Added Chemicals.

A NaOtBu-O -mediated oxidative dehomologation of homoallylic alcohols into structurally different carboxylic acids through direct oxidative cleavage of either the C(sp )-C(sp ) or C(sp )-C(sp ) bond utilizing enolate chemistry was demonstrated. Furthermore, under transition-metal-free conditions, this protocol has been applied to convert terpene as biomass feedstock into value-added chemicals.
