The study investigates the enzymatic resolution of norbornene carboxylic acids, norbornenylmethanols, and -methyl- amines using Porcine Pancreatic Lipase (PPL) in organic solvents. The key chemicals involved include norbornyl- and norbornenylnethanols, which undergo PPL-catalyzed transesterification in methyl acetate to yield corresponding acetates and methanols of high enantiomeric purity. Iodolactone 18 is highlighted as a substrate for synthesizing both enantiomers of endo-norbornene lactone via transesterification. The study also explores the influence of structural variations on the efficiency of PPL-catalyzed resolution, using lactone methanols 21, 23, 25, and 28. Other chemicals like methyl propionate and butyrate are used as solvents, while PPL serves as the catalyst. The results demonstrate the potential of PPL for resolving chiral compounds, with varying enantioselectivity and reaction rates depending on the substrate structure.
