ABSTRACT
Oxo-bridged dibenzoazocines are furnished within a single synthetic step at room temperature via ruthenium-catalyzed [4 + 3]-cycloannulation of aza-ortho-quinone methides with carbonyl ylides. Exclusive diastereoselectivity, excellent yield, mild reaction conditions, and broad substrate scope are distinguishing features of this protocol. The product could be prepared on a gram scale and could be further functionalized into diverse substituted dihydroisobenzofuran derivatives and a dibenzoazocine scaffold.
