  摘要：

  An efficient regioselective synthesis of polycyclic diheteroaryl[b,d]pyrans and diheteroaryl[c,e][1,2]diazepines has been reported through ring transformation reactions of 2-oxo-2,5-dihydrothiochromeno [4,3-b]pyrans (3,4), 2-oxo-5,6-dihydro-2H-benzo[b]pyrano[2,3-d]oxepine/thiepine (8, 9) and 6-oxo-3,6-dihydro-2H-naphtho[1,2-b]pyrano[2,3-d]oxepine (15) by hydrazine, at ambient and reflux temperature. Nine compounds viz 5a,b; 10a,c,d; 12b; 13b; 16 and 1-methylthio-5,6-dihydrobenzo[f]quinoline (0.1-100 mu M) were screened for their cytotoxicity in normal (IEC-6), carcinoma (Colo-205) and HepG2 cell lines. None of the compounds showed cytotoxicity in normal IEC-6 cells while 10a,d and 16 resulted in killing of Colo-205 cells with IC50 ranging 20-60 mu M while 10c and 13b caused killing of HepG2 cells with IC50 values ranging 60-80 mu M concentration. Further, 10a,d and 16 caused apoptosis through a cascade of mitochondrial pathway in Colo-205 cells indicating anticancerous potential against intestinal cancer. Interestingly, compounds 10c and 13b exhibited apoptosis through mitochondrial pathway in HepG2 cells suggesting anticancer activity against hepatic cancer. (C) 2014 Elsevier Masson SAS.

  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

  An efficient and concise route for the construction of thiochromene based oxahelicenes in which heteroatoms are located on the outer helix through base-induced ring transformation of 4-sec.amino-2-oxo-2,5-dihydrothiochromeno[4,3-b]pyran-3-carbonitriles by thiochroman-4-one, 1-indanone and 2-indanone separately has been described. The X-ray studies for P and 4a show the formation of supramolecular structures through weak C–H⋯O and C–H⋯N intermolecular interactions. Supramolecular chains in 6a through C–H⋯N and π⋯π and in 7via C–H⋯π and π⋯π weak and intermolecular interactions have been observed. The detail analyses of Hirschfeld surface and fingerprint plots gave a comparative picture of the modes of non-covalent interactions in the newly synthesized compounds. The stabilization energies associated with these weak interactions have been estimated using DFT and AIM theory calculations.
