Two examples follow which are drawn to emphasize how suprafacial addition occurs. The prefix exo is reserved for the isomer with the substituent located farthest or anti to the longest bridge. In the second example suprafacial approach of a dienophile to the 25 carbons of transtrans -24-hexadiene is seen to lead to a product with two methyl groups on the same side of the cyclohexene ring. The endo and exo products are really two different diastereomers.
Beta and Y-type zeolites exhibit higher activity because of their large three-dimensional channels.
Endoexo isomerism is a special type of stereoisomerism found in organic compounds with a substituent on a bridged ring system. Translations in context of endo in English-German from Reverso Context. 3 This is because of the interaction and coupling with the H-5 and H-6 as displayed in Figure 1. Surface passivation of Hβ confirms that the reaction proceeds in the inner channels.

The Diels-Alder reaction between cyclopentadiene and maleic anhydride can produce two possible products the endo and the exo adducts. This video also helps you to see when you get 1 or 2 different constitutional isomers.
The ENDO product is the one where the outside groups on the diene are on the SAME side of the 6-membered ring as the electron withdrawing group EWG.
A peak at 300 ppm would appear in the exo isomer spectra as opposed to a peak at 360 ppm as shown in the observed endo product. The Diels-Alder reaction between cyclopentadiene and maleic anhydride can produce two possible products the endo and the exo adducts. The exo isomer would possess a triplet around 350 ppm due to the difference in dihedral angle between the hydrogen molecules of H-1 and H-4 and H-5 and H-6 Figure 1.

This is tentatively assigned as the endo isomer and on base treatment it isomerizes to a new compound identified as the exo isomer. There is usually a temperature change. For example when a bonfire burns it. In general endo is the major product because it is formed when the electron-withdrawing groups of the dienophile are pointing towards the π electrons of the diene.

If you think about it you can see that when two rings fuse together to make a third four new stereocenters can be created.

What does endo-isomer mean. The ENDO product is the one where the outside groups on the diene are on the SAME side of the 6-membered ring as the electron withdrawing group EWG. This is because although the hydrogens of the maleic anhydride must be cis in the product there are two possible arrangements where this is true. Since each chiral centre could have two possible configurations there are sixteen possible stereoisomers that could result in the reaction shown above.
