A novel NHC-catalyzed annulation protocol for the asym. synthesis of biol. important β-lactam fused spirocyclopentane oxindoles with four contiguous stereocenters, including two quaternary carbon centers, was developed. Alternatively, spirocyclopentane oxindoles containing an enaminone moiety can be achieved using the same starting materials, isatin-derived enals, and N-sulfonyl ketimines, in the presence of a slightly different NHC catalytic system. This switchable annulation strategy enables the selective assembly of both heterocyclic scaffolds with good yields and excellent enantioselectivities for a broad range of substrates.
In some applications, this compound(1787246-78-9)Application of 1787246-78-9 is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
