✦ Synopsis

Reaction of 2-chloro-l-phenacylpyridinium bromide la with KSCN led to 2-aminothiazolo[3,2-a]pyridinium salts 4a,b thus opening a novel route to fused thiazoles. In reaction with KSCN oxazolo[3,2-a]pyridinium perchlorate 2a was converted to thiocyanate 2b. Crystal structures of thiocyanates 2b and 4b were determined.
