A Convenient Synthesis of 3-Cyano-2-methylpyridines under Ultrasonic Irradiation

Shibata, Katsuyoshi,Urano, Katsuyoshi,Matsui, Masaki

, p. 2199 - 2200 (1988)

Ultrasonic irradiation of α,β-unsaturated carbonyl compounds 1a-i with acetonitrile in the presence of pottasium t-butoxide gave 3-cyano-2-methylpyridines 2a-i in moderate to good yields.The pyridines are produced by a Michael reaction of 3-iminobutanonitrile, an acetonitrile dimer, to the substrates 1a-i.
