摘要：

Recent publications from our laboratory have introduced a new general strategy for oxapolycyclic ring synthesis in which a rhodium(II)-catalyzed tandem cyclization-cyclo-addition reaction represents the central element.1 For ongoing studies to further implement and develop this strategy, we required a general route to a-diazo 1,3-di-ketones, which serve as the precursors for carbonyl ylide dipoles of type 2.
