An experimental and theoretical study of the comparative reactivity and selectivity of the Diels-Alder reactions of para-benzoquinones and three nitrogen derivatives have been performed. The mono-oximes derivatives do not react under the tested reaction conditions, whereas the tosylated mono-oximes react slowly. However, the mono N-tosyl imines show excellent reactivity, and superior to the parent parabenzoquinones. DFT calculations support these experimental results.

Addition of cyclopentadiene to unsubstituted O-acyl-1,4-benzoquinone monooximes or their 2- or 3-methyl derivatives across the double bond of the quinone ring yielded the only endo-Z isomer, in spite of the possibility for isomerization around the C=N bon
