✦ Synopsis

Abstract

Using the double Michael condensation technique with divinyl ketone recently described^1^, as well as the dialkylation method^2^, we have prepared the compounds I, II and III. No syntheses of linear dispiro‐ and trispiro‐hydrocarbons embodying the 6‐membered carbocyclic ring only, have yet been reported ^3, 4, 5^.
