The reaction of Schiff base and indole catalyzed by iodine in DMA, subsequently treated with DDQ, gave indolo[3,2‐c]quinoline derivatives in good yields. The structure of 3e was confirmed by X‐ray diffraction analysis.

A microwave-assisted, one-pot three-component aza-Diels–Alder reaction strategy has been developed for the synthesis of some complex spiroquinoline derivatives from 1-aminonaphthalene, aromaticaldehyde, and 5-benzylidene-1,3-dimethyl pyrimidine-2,4,6-trione under catalyst- and solvent-free conditions.

Thermal analyses of some Schiff bases, derivative of alpha-napthylamine, were performed by the DSC, TG and DTA techniques. The thermograms were used to determine various kinetic parameters, such as the order of degradation (n), energy of activation (E), frequency factor (A), and entropy change (Delta S), by the Freeman-Carroll method.

A new strategy for synthesis of imines using the approach of release of H2 has been developed. This oxidant- and acceptor-free Pd/Ccatalysis protocol is further applied to synthesis of benzoxazoles, benzimidazoles, and benzothiazoles through a one-pot cascade reaction with notably high yields.
