Access to dihydropyridinones and spirooxindoles: application of N-heterocyclic carbene-catalyzed [3+3] annulation of enals and oxindole-derived enals with 2-aminoacrylates.

Chemical communications (Cambridge, England)

Zhao LL, Li XS, Cao LL, Zhang R, Shi XQ, Qi J.
PMID: 28513660
Chem Commun (Camb). 2017 May 30;53(44):5985-5988. doi: 10.1039/c7cc02753b.

A strategy for the NHC-catalyzed synthesis of dihydropyridinones and spirooxindoles has been developed via [3+3] annulation reactions of enals or isatin-derived enals with 2-aminoacrylates under oxidative conditions. In this efficient strategy, the 2-aminoacrylates served as nucleophiles. Modifying the standard...
