13. Explain that the synthesis of pharmaceuticals often requires the production of a single optical isomer. Explain that synthetic molecules often contain a mixture of optical isomers, whereas natural molecules often have only one optical isomer. Explain that the synthesis of a pharmaceutical that is a single optical isomer increases costs, reduces side effects and improves pharmacological activity. Describe strategies for the synthesis of a pharmaceutical with a single optical isomer. Chirality in Pharmaceutical Synthesis
