5-Alkyl-2-(p-tolylsulfonyl)pyridines by Regioselective Cyano Cycloaddition
Rueffer, Ursula,Breitmaier, Eberhard
, p. 623 - 625 (2007/10/02)
5-Alkyl-2-(p-tolylsulfonyl)pyridines 4 are obtained in good yields at room temperature by cyano cycloaddition of p-toluenesulfonyl cyanide 2 to 2-alkyl-1-ethoxy-1,3-butadienes 1, followed by aromatization of the intermediate dihydropyridine 3 via an
