Human cancer and other clinical trials under development employing combretastatin A-4 phosphate (1b, CA4P) should benefit from the availability of a [11C]-labeled derivative for positron emission tomography (PET). In order to obtain a suitable precursor for addition of a [11C]methyl group at the penultimate step, several new synthetic pathways to CA4P were evaluated. Geometrical isomerization (Z to
