  4-morpholino-11H-thieno[2',3':5,6]pyrimido[1,2-b]isoquinolin-11-one 在 sodium hydroxide 作用下， 以 甲醇 为溶剂， 反应 12.0h， 以100%的产率得到2-(4-oxo-3,4-dihydrothieno[3,2-b]pyrimidin-2-ylmethyl)benzoic acid

  Synthesis of substituted 4-aminothieno[2,3-d]-, 4-aminothieno[3,2-d]- and 4-aminothieno[3,4-d]pyrimidines

  摘要：

  A study was carried out on the nucleophilic cleavage of the lactam bond in 4-amino(pyrrolidino, piperidino, morpolino)thieno[2,3-d]-, -[3,2-d]-, and -[3,4-d]pyrimido[1,2-b]isoquinolin-11-ones. This bond is readily cleaved upon heating in methanolic NaOH at reflux for 1-2 h to give previously unreported 4-amino-2-(o-carboxyphenylmethyl)thienopyrimidines. Replacement of the amine group by an OH group is possible under the reaction conditions, leading to the corresponding, already reported 2-(o-carboxyphenylmethyl)-4-oxothienopyrimidines. Prolonged refluxing (8-12 h) resulted in oxothienopyrimidines as the major products of the transformations of all the thienopyrimido-isoquinolinones studied. Biological activity predictions of these new products were compared in silico.

  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.
