Expeditious synthesis of 1,3,4-oxadiazole derivatives via sydnones
The clean cyclization of chalcones (1a–c/2a–c) with hydrazine hydrate under microwave irradiation afforded pyrazolines derivatised with sydnone (3d–i/4d–i), which underwent 1,3-dipolar cyclo-addition with acetic anhydride to form pyrazolines appended with 1,3,4-oxadiazoles (5g–l/6g–l). The newly syn...
