Asymmetric Catalysis, Biocatalysis, and Resolution Routes to Chiral Purity
Producing optically pure chiral building blocks requires precise chemical control to favor the formation of one enantiomer over another. Chemical manufacturers employ three primary technological methodologies to commercialize these building blocks: asymmetric synthesis, biocatalysis, and chiral resolution. Selecting the optimal production pathway depends on target molecule complexity, required purity levels, and batch-scale economic considerations.
Asymmetric synthesis uses chiral transition-metal catalysts or organocatalysts to selectively build stereocenters from achiral precursors. Biocatalysis utilizes engineered enzymes—such as transaminases, ketoreductases, and lipases—to carry out highly stereoselective transformations under mild, environmentally friendly reaction conditions. Meanwhile, classic chiral resolution relies on separating racemic mixtures via diastereomeric crystallization or simulated moving bed (SMB) chromatography.
