Microwave-assisted synthesis of some 3,5-arylated 2-pyrazolines
Azarifar, Davood,Ghasemnejad, Hassan
, p. 642 - 648 (2003)
Condensation of 2-acetylnaphthalene with benzaldehydes under microwave irradiation affords chalcones which undergo facile and clean cyclizations with hydrazines RNHNH2 (R= H, Ph, Ac) to afford 3,5-arylated 2-pyrazolines in quantitative yields,
