Webequilibrium with the s-cis conformation does, however, exist, which is enough to allow the Diels-Alder reaction to take place. In the case of cyclic dienes, the diene is locked in the reactive s-cis conformation. For this reason, cyclic dienes are especially reactive in Diels-Alder reactions. Figure 3. s-cis and s-trans Dienes + WebStep 1: Cis and trans isomers The stereoisomers in which both functional groups are present on the same side of the plane are called cis isomers. The stereoisomers in which both functional groups are present on the opposite side of the plane are trans-isomers.

Cis–trans isomerism, also known as geometric isomerism or configurational isomerism, is a term used in chemistry that concerns the spatial arrangement of atoms within molecules.
