ChemInform Abstract: 1,3-Dipolar Cycloaddition of Ethyl Diazoacetate with (E)-3-Arylidenechroman-4-ones. A New Access to Spirocyclopropane Derivatives

Dipolarophiles (I) react with ethyl diazoacetate (II) at the exocyclic double bond of (I), regardless of the electronic nature of the p‐substituents on the aryl group of (I), to provide the single spiro‐compounds (III).
