  Synthesis of [18-11C/(13C)]linoleic acid

  摘要：

  A method for the preparation of [18-C-11]linoleic acid is described. A highly reactive zerovalent copper complex was prepared from lithium (2-thienyl)iodocuprate reduced by lithium naphtalenide. This copper complex was used in a coupling reaction between 17-iodo-cis,cis-9,12-heptadecadienoic acid tert-butyl ester and [C-11]methyl iodide to form [18-C-11]linoleic acid tert-butyl ester as intermediate. The tert-butyl ester protecting group was rapidly removed with trifluoroacetic acid, affording [18-C-11]linoleic acid in 48% radiochemical yield. In a typical run starting with 27 GBq of [C-11]methyl iodide, 2.9 GBq [18-C-11]linoleic acid was obtained within 44 min from the end of radionuclide production.
