Abstract Using adamantane-1,3-diamine and 3,5-di-tert-butylsalicylic aldehyde as raw materials, the generated salen aluminum complex was characterized by 1H, 13C NMR spectroscopy and elemental analysis. After isopropyl alcohol activation treatment, the complex has good activity (70.3-95.6%), which can provide poly(D,L-lactide) with a P m of 0.87 for rac-lactide. Graphical Abstract
