Stereoselective halocyclization of pro-chiral 2,2-bishydroxymethyl-1-tetralone derivatives with N-halosuccinamides afforded an interesting tricyclic scaffold found in many naturally occurring hasubanan alkaloids. Enantiopuretricyclic scaffolds are synthesized by using enzymatic kinetic resolution (EKR) of the parent racemic compound. Microbial ketoreductase (Geotrichum candidum, Aspergillus niger
