A Three-Step Pyridoannelation of Carbonyl Compounds
Marchetti, Mauro
, p. 1761 - 1765 (2007/10/02)
The elaboration of a pyridine nucleus onto an α-methylene carbonyl compound can be accomplished through a three step reaction sequence based on the regiospecific alkylation of N,N-dimethylhydrazones with bromoethyl-1,3-dioxolane.Scope and limitations of the new method are considered.
