Stereocontrolling refers to the ability of a molecule or chemical reaction to control the stereochemistry of its product(s). Synonyms for stereocontrolling might include stereoselective, stereospecific, or enantioselective, as all of these terms describe the ability to control the stereochemistry of a reaction or molecule. Other possible synonyms might include chirality, which refers to the property of a molecule that has a non-superimposable mirror image, or regioselectivity, which describes a chemical reaction that selectively produces a certain product based on the position of a substituent. Regardless of the specific terminology used, the concept of stereochemistry is crucial in many fields of chemistry and biochemistry, and plays a key role in the development of new drugs and materials.
