    • The acylnitroso Diels-Alder cycloadducts used in this report were all racemic, and therefore all the products generated were racemic as well. Only one enantiomer was shown for every compound to simplify the schemes and tables.

    • 1H NMR. The bulky tert-butyl group in 18 may have had a significant effect on the conformation of the molecule, leading to the unusual NMR pattern.

    • note
    • There is no direct evidence to date as to how reductive transmetalation between InI and palladium π-allyl complex occurs (i.e., whether InI approaches from the same or opposite face of the palladium). However, an indication that the allylindium species are at equilibrium has been observed from our results with the N-carbamate protected cycloadducts (vide infra).

    • For the lack of a better way to clarify the drawing of the transition states, we actually used the mirror image of 28 in transition states 30 and 31. Since the compounds are racemic, it does not affect the results.
