Phosphine-catalyzed [5+1] annulation reaction of Morita-Baylis-Hillman (MBH) carbonates with 1,3-dicarbonyl compounds has been developed, producing biologically interesting spirocyclohexene derivatives in high yields with moderate to excellent diastereoselectivities. The annulation was achieved through sequential 1,6-conjugate addition/nucleophilic substu- tion reaction of phosphine ylides with dinucleophiles.

Key words: phosphine catalysis, Morita-Baylis-Hillman carbonate, 1,3-dicarbonyl compound, dinucleophile, spirocyclo- hexene
