    A non-catalytic approach to the synthesis of 5,6-dihydrobenzo[h]quinolines
    摘要:
    A concise synthesis of highly functionalized 5,6-dihydrobenzo[h]quinoline-3-carbonitriles is delineated through base induced ring transformation of 4-sec-amino-2-oxo-5,6-dihydro-2H-benzo[h]chromene-3-carbonitriles with S-methylisothiourea sulfate and 1-carboxamidinepyrazole hydrochloride, separately, in DMF. Under analogous reaction conditions the ring transformation of 4-sec-amino-2-oxo-5,6-dihydro-2H-benzo[h]chromene-3-carbonitriles by formamidine acetate provided 4-sec-amino-benzo[h]quinoline-3-carbonitriles in moderate yields, while with benzamidine hydrochloride, the reaction followed the same mechanism to yield 2-phenyl-4-sec-amino-5,6-dihydrobenzo[h]quinoline-3-carbonitriles.

    Highly congested pyrazole and imidazole ring containing heterocycles were studied for their photophysical and electrochemical properties. TDDFT calculations of the molecules were carried out using B3LYP/G(d,p) level theory in DMF medium and the results were in good agreement with the experimental values. The imidazole derivatives showed a red shifted absorption peak (λmax, 455–474 nm) and higher molar
