Total synthesis and antiangiogenic activity of cyclopentane analogues of fumagillol

Novel cyclopentane analogues of fumagillol were synthesized and their endothelial cell proliferation inhibitory activities were evaluated. The cyclopentane-fumagillol derivatives were synthesized from (−)-2,3-O-isopropylidene-d-erythronolactone via stereoselective glycolate Claisen rearrangement and intramolecular ester enolate alkylation as key steps.
