The synthetic route is as follows.
General procedure: To a solution of acetophenone or isatin (5 mmol) in THF (10 mL), BF3¡¤OEt2 (7.5 mmol) was added at 0C under the atmosphere of N2 and the mixture was stirred for 10 minutes. To the cooled mixture, anhydrous hydrazine (7.5 mmol) was added in one portion and the reaction mixture was stirred at 0C under the atmosphere of N2 for 30 min. The reaction was quenched by the addition of a saturated solution of NH4Cl (4 mL), extracted by ethyl acetate (3 ¡Á 15 mL) and purified by column chromatography (ethyl acetate-CH2Cl2; 3 : 7) to afford hydrazones 2-22.
