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
