AlkaloidsU 0600 An Improved Synthesis of β-Nicotyrine from the Dehydrogenation of Nicotine:

Comparison of Conventional and Microwave-Assisted Reactions. — β-Nicotyrine (II) is prepared by MnO2-catalyzed dehydrogenation of (-)-nicotine (I) both in refluxing solvents and under microwave irradiation. The microwave assisted technique provides superior yields in significantly shorter reaction times. — (WEI, X.; CROOKS*, P. A.; Synth. Commun. 33 (2003) 19, 3305-3315; Div. Pharm. Sci., Coll.
