An oxazolidone auxiliary-controlled asymmetric Nazarov reaction has been applied to the synthesis of the cyclopentyl-fused pyrrole core of roseophilins. Additionally, a concise synthetic route to the pyrrole-furan biaryl fragment required in the synthesis of the recently isolated dechlororoseophilin is described. It is anticipated that these two syntheses can be combined in future efforts to provide
