resulting esters were cyclized to unsaturated 2‐ and 3‐furylmacrolactones by ringclosingmetathesis using Grubbs catalyst I. Hydrolysis of the macrolactone 4b with NaOH led to the furylalkenoic acid and reaction of 4c with tert‐butyllithium gave a tert‐butyl ketone. Some of the resulting compounds were tested in the MTT assay for their cytotoxic activities against HL 60 cells and at the National Cancer
