The new molecular construction technique, unveiled in a Science online First Release paper on February 2, 2017, represents a significant milestone in chiral chemistry. It creates a structure that chemists call an α–chiral center, thereby enabling the synthesis of a great variety of potentially valuable chiral drugs and other products. At the same time—unlike most previous chirality-inducing reactions—it requires only inexpensive and widely available starting chemicals.

Isobutyric acid is also found in nature, and bacteria and other organisms have evolved enzymes that convert it to natural chiral molecules. In the past few decades, pharmaceutical chemists have learned to harness some of these natural enzyme reactions—using genetically engineered bacteria—to help them build chiral drug molecules. However, these enzyme-driven reactions are restricted to isobutyric acid as a starting molecule and are very limited in the chiral molecules they can yield. The new ligand/catalyst, while essentially mimicking nature’s synthetic feat, is much more versatile.

Why Enzymes Are Used in Drug Synthesis

Biocatalysis is the use of natural catalysts (e.g., enzymes), in place of chemical catalysts in synthetic processes. This enables new, sustainable routes of production for intermediates and APIs. It is an important tool for medicinal, process and polymer chemists, allowing the development of efficient and highly attractive organic synthetic processes on an industrial scale.

The continuous interest in developing pure chiral drugs boosts the development of new asymmetric synthesis methods, but sometimes the focus on this development clouds or even neglects common methods.Chiral Drugs

Overview of Chirality and Chiral Drugs

One advantage of enzymes in organic synthesis is their unique selective properties, which give a number of commercial benefits, such as better production of single stereoisomers, fewer side reactions, fewer reprocessing/purification steps and easier product separation.
