ABSTRACT
The Vilsmeier Haack reaction upon 4-hydroxy-2-methyl quinolines yielded some unprecedented compounds. Elucidation of the structure of hitherto unknown novel 4-chloro-3-formyl-2(vinyl-1-ol)quinolines and 3-formyl-4-hydroxy-2-methyl quinolines by NMR and Mass Spectroscopic methods is reported.
