  On the reaction of 2-amino-4-thiazoliniminium salts with active methylene compounds

  摘要：

  The easily available 2-amino-4-thiazoliniminium salts 6 react with different types of active methylene compounds. Whereas 2-amino-4-cyanomethylene-4,5-dihydrothiazoles 13 and 14 are formed with malononitrile (11) or ethyl cyanoacetate (12) in the presence of bases, acetyl acetone (15) and ethyl acetic acetate (16) afford 2-amino-thiazolo[4,5-b]pyridines 21 and 22, resp. The structures of the new compounds 13, 14, 21 and 22 have been elucidated by means of analytical and spectroscopic methods and confirmed by some chemical reactions.
