The cycloaddition reaction of 5‐amino‐ v ‐triazolines 2 with thiazolium‐4‐olates 1 affords two isomeric cycloadducts 3 and 4 . A synthetic utilization has been achieved by their desulfuration: The cycloadducts 3 and 4 are catalytically transformed with Raney nickel to pyridinones 5 . The acid‐catalized rearrangement of 3 and 4 affords the 8‐thia‐6‐azabicyclo[3.2.1]‐octane derivatives 6 .
