  摘要：

  Syntheses are given for previously unreported 4-chloro derivatives of 4H-thieno[3',2':5,6]- and 4H-thieno[2',3':5,6]pyrimido[1,2-b]isoquinolines and the reactions of these compounds with N- and S-nucleophiles were studied. The spectral characteristics and biological activity of the positional isomers were compared. The electron spectra most clearly reflect the differences related to the position of the sulfur atom in these quasiaromatic systems.

  Treatment of 2-(4-oxo-3,4-dihydrothieno[2,3-d]-and-[3,2-d]pyrimidin-2-ylmethyl)benzoic acids and 2-(4-oxo-3,4-dihydro-2-quinazolinylmethyl)benzoic acid with acetic anhydride gave thieno[3',2':5,6]-and-[2',3':5,6]pyrimido[1,2-b]isoquinoline-4,11-diones and isoquino[2,3-a]quinazoline-5,12-dione respectively. NMR spectroscopy showed that an intramolecular acylation of the above acids occurs at the atom N-1 of the pyrimidinone part of the bicycle.
