  摘要：

  6-Amino-thiazolo[4,5-c]isothiazole derivatives 4 are obtained by addition of hydrogen sulfide to the 4-Amino-thiazoline-5-carbonitrile 2 followed by cyclooxidation of the intermediate thioamides 3. In the presence of sodium sulfite the hydrolysis of the 4-amino-2-methylthio-thiazolium salts 5 derived from the title compounds 1 yields the 4-amino-thiazolin-2-ones 6. By their further hydrolysis the 2,4-dioxo-thiazolidin-5-carboxamides 8 are formed. The 2-oxo-and 2-thioxo-thiazolo [4,5-d]pyrimidin-7-ones and -thiones available from 1 undergo ring opening by hydrolysis to give the substituted 4-amino-6-oxo- and 4-amino-6-thioxo-pyrimidine-5-thiols 15a-h and 13i-e. They have been isolated as their disulfides 14 or 5-alkyl derivatives i.e. the substituted 4-amino-5-alkylthiopyrimidin-6-ones and -thiones 16. In analogy, the intermediate 6-amino-7-oxo-thiazolo[4,5-d] pyrimidin-2-thione 18 and the 7-amino-thiazolo[4,5-d]-pyrimidin-2-thione 24 derived from 1 react by ring cleavage to yield the 1,4- and 4,6-diamino-pyrimidin-5-thiole derivatives 22 and 27, respectively, isolated as their disulfides or alkylthio-derivatives. From the pyrimidine 16b the pyrimido[5,4-b]1,4-thiazine derivative 18 can be obtained.
