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

Nano aluminium nitride in the presence of water acts as solid source of ammonia, which is used for the preparation of 1,4-dihydropyridines and bis-(1,4-dihydropyridines). An efficient and simple procedure for the one-pot synthesis of 1,4-dihydropyridine and bis-(1,4-dihydropyridine) derivatives was achieved by combination of methyl acetoacetate or ethyl acetoacetate with aldehydes or dialdehydes and aluminium nitride at 80 degrees C in water in high purity and good yields.
