Chemistry · L5 · Catalytic asymmetric synthesis vs racemic resolution

Contrasts the classical route — synthesize a racemic mixture then resolve it, discarding the unwanted enantiomer — with catalytic asymmetric synthesis, where a chiral catalyst delivers the desired enantiomer directly and avoids that built-in 50% waste ceiling.
