And the E2 reaction can be a good example of a stereospecific reaction. On the left, we have our substrate, and we have these two phenyl groups here • A stereoselective reaction is one in which a single reactant can give two or more stereoisomeric products, and one or more of these products is preferred over the others – even if the preference is very small.

Regioselectivity in Radical Reactions of Carbohydrates In a stereospecific reaction, the stereochemistry of the substrate determines the stereochemistry of the product. An enantioselective reaction is selective for the formation of one enantiomer over another A stereoselective reaction is selective for the formation of one stereoisomer over another. We will talk about this particular reaction in more detail later A regioselective reaction is selective for the formation of one constitutional isomer (“regioisomer”) over another.
