From Ring-Expansion to Ring-Contraction: Synthesis of γ-Lactones from Cyclobutanols and Relative Stability of Five- and Six-Membered Endoperoxides toward Organic Bases

Autor: Laurent Ferrié, Nicolas Jamey

Publikováno v: Synthesis. 54:2816-2824

Cyclobutanols undergo ring expansion with molecular oxygen in the presence of Co(acac)2 to afford 1,2-dioxane-hemiperoxyketals. In the course of acylation, we observed that endoperoxides rearranged into γ-lactone in the presence of triethylamine. Th

Cyclobutanols undergo an oxidative ring expansion into 1,2-dioxanols by using Co(acac)2 and triplet oxygen (3O2) as radical promoters. The formation of an alkoxy radical drives to the regioselective break of the strained ring with stabilization of a
