    • In general, the DA reaction requires opposite electronic features of the substituents at the diene and the dienophile ends for the reaction to be reasonably fast. Therefore, the mechanism of these polar DA reactions can be located in the borderline between a highly asynchronous but concerted mechanism and a stepwise process with a large ionic character: L.R.

    • note
    • Our results are in accordance with a previous related study (Ref. 6e), showing that best yields are obtained with the trifluoromethanesulfonyl protected substrate. For the rest of N-substituted derivatives, slightly different reactivities were observed as a consequence of differences in diene, dienophile and reaction conditions; with less discrimination at the very high temperature of our thermal process.
