The synthesis of bifunctional pyridine and quinolione derivatives were investigated using terephthalic and isophthalic aldehydes as a precursor. The reaction proceeds under microwave irradiation with good yield (70–92%) and short reaction time (7–9 min.). We provide a rapid and efficient method of synthesizing a range of bifunctional monocyclic and bicyclic products related to 1,4-dihydropyridines

The synthesis of bifunctionalpyridine, pyrimidine, pyridone, quinoline and acridine derivatives was investigated using dialdehyde as a precursor. A rapid and efficient method was developed for the synthesis of a range of bifunctional monocyclic, bicyclic and tricyclic products related to 1,4-DHPs with the aim of finding new classes of biologically active compounds.

Abstract The synthesis of various substituted 1,4‐dihydropyridines has been achieved by the reaction of aldehydes, ethyl/methyl acetoacetates, and ammonium acetate in water using phase‐transfer catalyst undermicrowaveirradiation. Compared to the classical Hantzsch's reaction conditions, this new method consistently has the advantage of good yields and short reaction times. Bifunctionalcompounds containing

A number of 2,6-dimethyl-3,5-bis(methoxycarbonyl)-4-substituted-1,4- dihydropyridines were synthesized and evaluated for pregnancy-interceptive activity in mated hamsters. Out of 24 compounds, 12, 15, 21, 22, 28, and 34 caused a marked reduction in the number of implantations when administered on days 3-8 postcoitum. In an in vitro competition assay, none of the compounds exhibited noticeable binding affinity for uterine progesterone receptors. The results reported here have helped to identify new leads for developing pregnancy-interceptive agents and the active compounds do not seem to elicit their interceptive effect through receptor-mediated inhibition of progesterone action in hamster uterus.
