Abstract
Combretastatin A‐4 (CA4) is a potent anti‐mitotic and vascular disrupting agent. Organic chemists have been working to optimize the synthesis of CA4 for the past 3 decades, with methods requiring hazardous solvents and harsh reaction conditions. Here, we report the synthesis of CA4 and a variety of stilbenes in an aqueous Wittig system. Potassium carbonate or lithium hydroxide were used as base in this Wittig reaction to give excellent yields of mixtures of E‐ and Z‐stilbenes. The synthesis of CA4 was achieved using tetrahydropyran (THP) or silyl protected phenolic aldehydes. The THP groups were removed using dilute acid whilst the silyl groups fortuitously fell off during work up.
