报道了有机膦催化的Morita-Baylis-Hillman (MBH)碳酸酯与1,3-二羰基化合物的[5+1]环化反应, 以高产率和中等至优秀的非对映选择性得到一系列具有潜在生物活性的螺环己烯衍生物. 该环化反应是通过膦叶立德用双亲核试剂的连续1,6-共轭加成/亲核取代反应实现的.

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
