The Diels-Alder (DA) reaction, first elucidated in the previous century, stands as a cornerstone of organic synthesis. This cycloaddition reaction involves the formation of a conjugated diene and a dienophile, typically an alkene, culminating in a substituted cyclohexene system. DA reactions are one of most useful techniques for creating carbon-carbon bonds. Furthermore, such reactions were fundamental in the creation of famous the Woodward-Hoffmann rules, a set of principles governing the stereochemistry of organic reactions. Of particular note for common DA reactions are their capacity to result in either an "endo" or "exo" isomer during the formation of the transition state. This results in two distinct products. More specifically, if we consider the reaction between cyclopentadiene and acrylonitrile (see Fig. ), the resulting products under ambient conditions are known provide endo and exo in equal proportion (i.e., no selectivity).
