An efficient synthetic route to citreochlorol analogs, halogenated polyketide secondary metabolites, is described. The key features are Krische's enantioselective carbonyl allylation, IBr-promoted cyclization, and regioselective epoxide opening. The importance of the route lies in the access of the versatile epoxy ether 14, which opens access to the citreochlorol monochloro derivatives 5 and 6.
