(3+2) Cycloaddition of N-benzylazomethine methylide with 4-arylidene-1H-imidazol-5(4H)-ones

4-Arylidene-1 H -imidazol-5(4 H )-ones react with N -benzylazomethine methylide under trifluoroacetic acid catalysis to form 9-aryl-1,3,7- triazaspiro[4.4]non-1-en-4-ones in 66–95% yields as one diastereomer in each case.
