Bioorg Med Chem Lett. 2020 Aug 1;30(15):127285. doi: 10.1016/j.bmcl.2020.127285. Epub 2020 May 26.

Abstract

It is known that 7-epitaxol has much stronger cytotoxicity than taxol does. However, the content of 7-epitaxol in yew is much less than taxol, which makes it more costly to obtain. We describe here a method to effectively convert taxol to 7-epitaxol. The key condition for reaction needs NaHCO3 in solvent acetonitrile (ACN). The conversion rate can be over 82%.

Keywords: 7-Epitaxol; Acetonitrile; Epimerization; HCO(3)(–); Taxol.
