was shown that the initial N-acylation of the tetrahydroquinolines was followed by a spontaneous [4+2]-cycloaddition of an N-acryloyl substituent to the furan ring. It was established that the intramolecular Diels–Alder reaction of furans is reversible, occurs stereoselectively as exo-addition, and led to target epoxyisoindolo[2,1-a]tetrahydroquinolines with moderate yields.

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.
Study of regioselectivity of intramolecular cyclization of N-(m-R-phenyl)- and N-(α-naphthyl)-2-allyl(methallyl)-6-carboxy-4-oxo-3-aza-10-oxatricyclo[5.2.1.01,5]dec-8-enes

.2.1.01,5]dec-8-enes in reactions with phosphoric acid was studied. The reactions of N-(m-R-phenyl)-substituted derivatives proceed nonregioselectively to form mixtures of 2-R- and 4-R-substituted isoindolo[2,1-a]quinolines, whereas the reactions of N-(α-naphthyl)-substituted derivatives occur regioselectively at the β position of the naphthyl fragment.
