Highly Selective Catalyst-Directed Pathways to Dihydropyrroles from Vinyldiazoacetates and Imines
摘要:
Copper-catalyzed reactions of vinyldiazoacetates with imines occur via a pathway in which the activated imine undergoes electrophilic addition to the vinyldiazo compound, whereas reactions catalyzed by rhodium(II) proceed through a metal carbene to an intermediate iminiumylide. Both pathways exhibit high stereoselectivities.
The invention relates to substituted nitrogen containing bicyclic heterocycles of the formula (I)
