In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Preparation of campholenal analogs: chirons for the lipophilic moiety of sandalwood-like odorant alcohols., published in 1992-08-13, which mentions a compound: 35836-73-8, Name is 2-((1R,5S)-6,6-Dimethylbicyclo[3.1.1]hept-2-en-2-yl)ethanol, Molecular C11H18O, Electric Literature of C11H18O.
In connection with structure-activity relationship studies, analogs of campholenal [(+)-I; R = Me], an important building block for sandalwood-like odorants, were prepared The five-membered-ring analogs I [R = Et, Pr, Bu, CH2CH2OR’, CH2CH2COMe, CH:CH2, CH2CH2CO2Et, CH2OMe, CH2OEt, CH2CH2CH2CO2Me, R’ = H, Me, SO2C6H4Me-p] were obtained by epoxidation of the corresponding α-pinene derivatives II, followed by catalytic ZnBr2 isomerization. The six-membered-ring skeleton III was obtained by ozonolysis of α-campholenyl acetate [(-)-IV], followed by intramol. aldol condensation. 13C-NMR assignments are given.
After consulting a lot of data, we found that this compound(35836-73-8)Electric Literature of C11H18O can be used in many types of reactions. And in most cases, this compound has more advantages.
