Tetrahydropyridines are generated from imines in the aza form of this reaction.
A pentadehydro modification of this reaction can be used to generate alpha-three-dehydrotoluenes. Derivatives of one reagent commonly used as a reactant in this reaction include ones named for Brassard and Rawal. Tetrahydropyridines are generated from imines in the aza form of this reaction. This reaction is particularly fast between (*) cyclopentadiene and maleic anhydride, and this reaction preferentially generates the product generated when the electron-withdrawing groups on one reactant points inward, called the "endo" configuration. For 10 points, name this [4+2] cycloaddition in which a six-membered ring is created from a diene and a dienophile.
A pentadehydro modification of this reaction can be used to generate alpha-three-dehydrotoluenes.
