Chemical synthesis of biodegradable stereoregular polyhydroxyalkanoates has the potential to reduce production costs, but achieving high isotacticity and molecular weight is challenging. Now efficient spiro-salen catalysts are developed to synthesize such polymers with high stereoselectivity from rac-β-butyrolactone.
