Herein, we describe a valuable method for the introduction of the [(18)F]CF3 group into arenes with highly improved specific activity by the reaction of [(18)F]trifluoromethane with aryl iodides or aryl boronic acids. This [(18)F]trifluoromethylation

Purpose All clinical 89Zr-immuno-PET studies are currently performed with the chelator desferrioxamine (DFO). This chelator provides hexadentate coordination to zirconium, leaving two coordination sites available for coordination with, e.g., water mo

Autor: Martin Berkheij, Dennis J. den Boer, Claudia Sewing, Jan H. van Maarseveen, Wouter I. Iwema Bakker, Jan Willem Terpstra, Lisan van der Sluis, Henk Hiemstra, Adri van den Hoogenband

Publikováno v: Tetrahedron Letters, 46(14), 2369-2371. Elsevier

A novel efficient synthetic route towards the pharmaceutically relevant 2-substituted piperazine class is described. The key step involves α-lithiation of N-Boc piperazines, followed by reaction with several electrophiles. To obtain high yields, in
