The cis- and trans-fused octahydropyrrolo[2,3-c]azepin-4(5H)-ones synthesis via aza-Cope-Mannich rearragement has been investigated. One of the most common aza-Cope-Mannich rearragements combines the cationic 2-aza-Cope rearrangement with a Mannich cyclization. This tandem reaction well fit for pyrrolidine compound array generations since is characterized by mild reaction conditions, diasteroselectivity, and a wide synthetic versatility. It provides easy access to acyl-substituted pyrrolidines, a structure commonly found in natural products such as alkaloids, and has been used in the synthesis of a number of them, notably strychnine and crinine
