The cycloaddition of diphenylnitrilimine with substituted cyclopentadienones leads to the formation of the title spirooxadiazoline derivatives 2 , in good yields. The reaction is examined on the basis of the frontier molecular orbitals of the reacting reagents. An X‐ray crystallographic analysis of the product 2b is made.
