• In esoteric targets, such as highly strained hydrocarbons like spiropentadiene, shown here, the rings can be identical. (wikipedia.org)
  • The 11-carbon bicyclic structure shown above, spiro[5.5]undecane, is also a fully carbocyclic spiro compound. (wikipedia.org)
  • 319f.846f Spiro compounds are present throughout the natural world, some cases of which have been exploited to provide tool compounds for biomedical study and to serve as scaffolds for the design of therapeutic agents with novel shapes. (wikipedia.org)
  • citation needed] As well, the spiro motif is present in various practical compound types (such as dyes), as well as in a wide variety of oligo- and polymeric materials designs, for the unique shapes and properties the spiro center imparts, e.g., in the design of electronically active materials in particular. (wikipedia.org)
  • citation needed] Bicyclic ring structures in organic chemistry that have two fully carbocyclic (all carbon) rings connected through just one atom are present both in natural products, as well as in esoteric targets of chemical synthesis. (wikipedia.org)
