Abstract
3-Hydroxyquinoline-4-carboxylic acids containing ethynyl moiety in the 6th and 8th positions were obtained for the fi rst time. A synthetic approach to aforementioned compounds based on the Sonogashira cross-coupling and the Pfi tzinger reaction was developed. Physicochemical properties of the newly synthesized structures were investigated.
