Abstract A new synthesis of cis-dihydro-rose oxide from elsholtzia oil is presented. The stereochemistry of catalytic hydrogenation of elsholtziol is discussed, and configurations of the diastereoisomers of the resulting tetrahydroelsholtziol have been deduced with the aid of gas chromatography, infrared spectroscopic analysis and conformational analysis. Stereochemical study of catalytic dehydration of tetrahydroelsholtziols indicates that the ...
