(Methoxymethyl)triphenylphosphonium chloride is used as a phase transfer catalyst and in the synthesis of taxol-A fragment. It is widely used in the synthesis of pharmaceutical product cephalotaxine, which is used as an antiviral and antitumor agent.
Wittig reaction (see Appendix 1) of the derived phosphorane with aldehydes and ketones gives enol ethers, readily hydrolyzed to homologous aldehydes. For an example (adamantanone to adamantanecarboxaldehyde), see: Chem. Ber., 95, 2514 (1962). For use of the reaction in the synthesis of hydroisoquinoline AMPA antagonists, see: J. Med. Chem., 39, 2219 (1996). Reaction with chiral 2,3-epoxyaldehydes provides an enantioselective synthesis of (E)-4-hydroxyalkenes: J. Chem. Soc., Chem. Commun., 232 (1993)./n
