Process for making tricyclodecenyl esters

Page/Page column 6; 7, (2008/12/04)
A practical, economical process for making tricyclodecenyl esters is disclosed. After reacting a lower carboxylic acid and a dicyclopentadiene in the presence of triflic acid to form the ester, the reaction mixture is distilled in the presence of a base to isolate a fragrance-quality tricyclodecenyl ester. Adding enough base to neutralize the triflic acid enables a distillation-only purification, facilitates starting material recovery, and avoids drawbacks of a basic workup.
Synthesis of esters by addition of carboxylic acids to cage cycloolefins

The thermal addition of monocarboxylic acids to cage bi-, tri-, tetra-, and pentacyclic hydrocarbons was carried out, and a highly efficient wasteless method of preparing esters of the corresponding alcohols was developed. The reaction has no need for Lewis acids as special catalysts since the initial acids themselves function as both catalyst and reagent. Orientation of the formyloxy and acyloxy groups in cycloolefin hydrocarbons was found, and the degree of regio- and stereoselectivity of the reaction was determined. A number of new esters of polycyclic alcohols were prepared. Some of them are of interest for perfumes.

The sensitized photooxidation of endo-5,6-dihydrodicyclopentadiene (2) by singulet oxygen gives via the corresponding hydroperoxide (10) exo-1-hydroxy-5,6-dihydrodicyclopentadiene (7a).Starting from exo-5,6-dihydrodicyclopentadiene (6) exo-5,6-dihydrodicyclopentadien-1-one (12) is formed.The 13C n.m.r. spectroscopical data of these compounds and of other hydroxy, alkoxy and acyloxy dihydrodicyclopentadiene derivatives are discussed in relation on their structure.
