Phosphine-Catalyzed (3 + 2)/(3 + 2) Sequential Annulation of γ‑Vinyl Allenoates: Access to Fused Carbocycles

The first (3 + 2)/(3 + 2) sequential annulation of γ-vinyl allenoates with alkylidenemalononitriles enabled by phosphine catalysis has been reported. A broad range of structurally dense tetra- and penta-substituted bicyclic­[3,3,0]­octene derivatives, containing a quaternary center and three sequent...
