A paper by Hermitage et al. concluded that one form of this reaction for N-aryl imines occurs in a stepwise mechanism with one reactant approaching the activated imine via a Bürgi-Dunitz trajectory. This reaction is often catalyzed by Lewis acids such as ytterbium (III) triflate. Its products tend to have their longest bridges with substituents that are cis oriented.

A paper by Hermitage et al. concluded that one form of this reaction for N-aryl imines occurs in a stepwise mechanism with one reactant approaching the activated imine via a Bürgi-Dunitz trajectory. This reaction is often catalyzed by Lewis acids such as ytterbium (III) triflate. Its products tend to have their longest bridges with substituents that are cis oriented. A particularly reactive reagent used in this reaction is named for (*) Danishefsky. The highest occupied and lowest unoccupied orbitals of the two reactants interact in the frontier orbital theory of this reaction. It has an aza variety and it can be used to produce cyclohexane from ethene and butadiene. This reaction generally follows the cis principle and endo addition rule. For 10 points, name this doubly-eponymous reaction that requires little energy and involves the 4+2 cycloaddition of a conjugated diene to a dienophile.
