Section 3.14 Cyclic hydrocarbons can contain more than one ring. Spirocyclic hydrocarbons are characterized by the presence of a single car bon that is common to two rings. Bicyclic alkanes contain two rings that share two or more atoms. 

Spirocyclic hydrocarbon (Section 3.14) A hydrocarbon in which a single carbon is common to two rings. 

Data published for three spirocyclic hydrocarbons have been selected 106-106b). Their recalculation also confirms the validity of the above-mentioned principles for polycyclic compounds (Table IX).

Organic molecnles in which one carbon atom is common to two rings are called spirocyclic componnds. The simplest spirocyclic hydrocarbon is spiropentane, a product of laboratory synthesis. More complicated spirocyclic hydrocarbons not only have been synthesized bnt also have been isolated from natnral sources. a-Alaskene, for example, occurs in the fragrant oil given off by the needles of the Alaskan yellow cedar one of its carbon atoms is common to both the six-membered ring and the five-membered ring.
