Merging oxidative dearomatization and aminocatalysis: one-pot enantioselective synthesis of tricyclic architectures.

The combination of oxidative dearomatization and trienamine/enamine activation in a single vessel is described. Under these conditions, a three-bond forming process generates functionalized tricyclic architectures with up to six contiguous stereocenters with excellent stereoselectivities from readily available planar substrates.
