The reactions of the 2-functionally substituted methylthiazol-4-one derivatives (1a-c) with N-arylmaleimides (2a, b) and ethyl acrylate have resulted in the synthesis of several new pyrrolo[2,3:4’,5’]lpyrrolo[2,1-b]thiazoles and thiazolo[2,3-a]pyridine derivatives. The structures of the synthesised compounds were assigned based on analytical and spectral data.
