The 1,3‐dipolar cycloaddition of an azomethineylide generated by a decarboxylative route from sarcosine and acenaphthenequinone to 7‐arylmethylidene‐3‐aryl‐3,4‐dihydro‐2H‐thiazolo[3,2‐a][1,3,5]triazin‐6(7H)‐ones afforded novel dispiro[acenaphthylene‐1,2′‐pyrrolidine]‐3′,7′ ′‐[1,3]thiazolo[3,2‐a][1,3,5]triazines in moderate yields. The structures of the products were determined and characterized thoroughly
