    • Since only two diastereoisomers were isolated, the origin of the diastereoselectivity was studied by computational method. The DFT calculations suggested that the Mannich reaction is stereospecific because of the rigid polycylic skeleton. The cis-fused [4.3.0] bicyclic structure is the only accessible product of the cyclization process. See the Supporting Information for details
