TL;DR: Intermolecularcycloadditions using diazodiones 12 and 13 with DMAD and arylacetylenes 16-18 again demonstrated that electronics play a key role in determining the outcome of the cycloaddition reactions.
Abstract: An evaluation of α-aryl-α-diazodiones in tandem carbonyl ylide formation−enantioselective [3 + 2]-cycloaddition reactions is described. Such substrates were designed to allow investigation of the electronic characteristics of the dipole upon asymmetric induction. Intramolecular cycloadditions (with a tethered alkene dipolarophile) were found to occur in good to quantitative yields, with a difference in ee exhibited by the two electronically different diazodiones 8 and 9. Intermolecular cycloadditions using diazodiones 12 and 13 with DMAD and arylacetylenes 16−18 again demonstrated that electronics play a key role in determining the outcome of the cycloaddition reactions. Enantioselectivities of up to 76% were observed.

Journal ArticleDOI
TL;DR: Asymmetric inductions up to 71% have been observed in a Pd catalyzed version of an intramolecular Alder ene reaction as discussed by the authors, where the inductions were obtained in the case of Pd-catalyst Alder Ene reactions.
