We herein disclose the first report of a first-row transition metal-catalyzed α,β-dehydrogenation of carbonyl compounds using allyl-nickel catalysis. This development overcomes several limitations of previously reported allyl-palladium-catalyzed oxidation, and is further leveraged for the development of an oxidative cycloalkenylation reaction that provides access to bicycloalkenones with fused, bridged, and spirocyclic ring systems using unactivated ketone and alkene precursors.
A REGIOSELECTIVE DIELS-ALDER SYNTHESIS OF ELLIPTICINE

The trimethylsilyl trifluoromethanesulfonate accelerated Diels-Alder reaction between 1,3-dimethyl-4-(phenylsulfonyl)-4H-furoindole (3) and 5,6-dihydropyridones (10) shows high regioselectivity, yielding carbazole 11 upon hydrolytic workup.Carbazole 11b has been successfully converted to the pyridocarbazole alkaloid ellipticine (1).
