摘要

The synthesis of combretastatin A4 (CA4) from commercially available inexpensive materials has been achieved via the Wittig reaction followed by irradiation of the (Z)/(E)-CA4 reaction mixture with sunlight. The method resulted in (Z)-CA4 in high yield. This method does not require protection of the phenolic hydroxy group. The synthesis is operationally simple and cost-efficient.
