Isoborneol is a bicyclic organic compound and a terpene derivative. The hydroxyl group in this compound is placed in an exo position. The endo diastereomer is called borneol .
Industrially, a racemic mixture of camphor is used, leading to a racemic mixture of borneol and isoborneol. The chirality can be controlled by changing the chirality of camphor: (+)-camphor gives (−)-isoborneol and (+)-borneol. [7] Reduction of camphor with sodium borohydride (fast and irreversible) gives instead the diastereomer isoborneol.
Isobornyl acetate is an organic compound consisting of the acetate ester or the terpenoid isoborneol. It is a colorless liquid with a pleasant pine-like scent, and it is produced on a multi-ton scale for this purpose. The compound is prepared by reaction of camphene with acetic acid in the presence of a strongly acidic catalyst such as sulfuric ...
2-Methylisoborneol (MIB) is an irregular monoterpene derived from the universal monoterpene precursor geranyl pyrophosphate.MIB and the irregular sesquiterpene geosmin together account for the majority of biologically-caused taste and odor outbreaks in drinking water worldwide. [1]
The rearrangement was first discovered in bicyclic terpenes for example the conversion of isoborneol to camphene: [8] Dehydration of Isoborneol to Camphene. The story of the rearrangement reveals that many scientists were puzzled with this and related reactions and its close relationship to the discovery of carbocations as intermediates. [9]
Bornyl acetate is a chemical compound. [1] Its molecular formula is C 12 H 20 O 2 and its molecular weight is 196.29 g/mol. It is the acetate ester of borneol.It is used as a food additive, [2] flavouring agent, and odour agent.
Their CAS numbers differ 3407-42-9 for IBCH and 4105-12-8 for isocamphyl cyclohexanol. The structure in the article refers to isocampheyl cyclohexanol that is derived from isocampheol. It does not have the methyl group attached to the bridge-head carbon which isoborneyl cyclohexanol (derived from isoborneol) should have.
