Abstract
Domino reaction of vinyl malonitriles (VMs) with 1,2-diaza-1,3-dienes (DDs) produce unprecedented 3a,4-dihydro-1H-pyrrolo[1,2-b]pyrazole systems in chemo- regio- and stereoselective fashion. This base promoted (DIPEA) one-pot transformation involving multiple steps implicates the formation of one new C–C bond, two C–N bonds and two new fused heterocyclic rings with total atom economyFile in questo prodotto:
