Diels-alder reaction uses
WebThe Diels-Alder reaction forms a six-carbon cycloalkene from two smaller carbon structures. Specifically, the two reactants are called the diene and dienophile. The simplest Diels-Alder reaction uses 1,3-butadiene and ethene. Ethene (the dienophile) performs a Diels-Alder reaction with 1,3-butadiene (the diene) to form cyclohexene.

WebThe 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.
