carbonate catalyzed anionic dominoreaction of thiazolium salts with salicylic aldehydes. It is presumed that the domino sequence includes Krohnke condensation, nucleophilic cyclization, and ANRORC (addition of nucleophile/ring opening/ring closure) steps. To the best of our knowledge, this is a first example of a multistep anionic dominoreaction incorporating an ANRORC transformation. The initial

A route towards chromenes, annulated with an imidazo[5,1-c][1,4]thiazine core through a base-promoted dominoreaction of thiazolium quaternary salts, has been developed. The synthesised compounds show high cytotoxic activity against human tumour cell lines.
