WitrynaAmerican Chemical Society WitrynaThe imino Diels-Alder (IDA) reaction may occur either by a concerted or stepwise process. The lowest-energy transition state for the concerted process places the imine lone pair (or coordinated Lewis acid) in an exo position. Thus, ( E) imines, in which the lone pair and larger imine carbon substituent are cis, tend to give exo products.
