Tang, Yitian published the artcileEfficient Synthesis of γ-Lactones by Cobalt-Catalyzed Carbonylative Ring Expansion of Oxetanes under Syngas Atmosphere, Formula: C6H10O2S, the publication is ChemCatChem (2020), 12(23), 5898-5902, database is CAplus.
A practical route from oxetanes or thietanes to γ-(thio)butyrolactones via solvated-proton-assisted cobalt-catalyzed carbonylative ring expansion under syngas atm. were reported. A wide variety of γ-(thio)butyrolactones were afforded in a good to excellent yields. The versatility of this method were well demonstrated in the synthesis of intermediates towards the natural product Arctigenin as well as the pharmaceuticals Baclofen and Montelukast. The observed promoting effect of glycol ether solvent were rationally interpreted.
