If all of the “outside” groups on the diene are the same as the “inside” groups, then there can’t be exo or endo.Butadiene itself, for example; the “inside” and “outside” groups are both hydrogens. If the dienophile lacks a substituent that can be distinguishe...

Shape recognition of alkylammonium ions by 1,3-bridged calix[5]arene crown-6 ethers: endo- vs exo-cavity complexation. A series of tri-O-substituted 1,3-bridged calix[5]arene crown-6 ethers bearing alkyl, arylalkyl, alkoxyalkyl, and alkoxycarbonylmethyl residues at the lowe......
Click the structures and reaction arrows in sequence to view the 3D models and animations respectively The endo product must have a lower energy transition state (not final structure!) than the exo product. This is why it forms more quickly. By looking at the HOMO and LUMO (frontier orbitals...
