Abstract

An efficient synthetic route to citreochlorol analogues, 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 accessing a versatile epoxy ether that enables the formation of citreochlorol monochloro derivatives.
