The total synthesis of a bis-cyclopropane analog of the antimitotic natural product (-)-disorazole C1 was accomplished in 23 steps and 1.1% overall yield. A vinyl cyclopropane cross-metathesis reaction generated a key (E)-alkene segment of the target molecule. IC50 determinations of (-)-CP2-disorazole C1 in human colon cancer cell lines indicated low nanomolar cytotoxic properties. Accordingly, this synthetic bioisostere represents the first biologically active disorazole analog not containing a conjugated diene or polyene substructure element.
