Synthesis of fully substituted pyrazoles via regio- and chemoselective metalations

Despotopoulou, Christina,Klier, Lydia,Knochel, Paul

, p. 3326 - 3329 (2009)

The full functionalization of the pyrazole ring was achieved by successive regioselective metalations using TMPMgCI-LiCI and TMP2Mg.2LiCI. Trapping with various electrophiles led to trisubstituted pyrazoles. An application to the synthesis of the acaricide Tebufenpyrad is reported.
