EFFECT OF SULFUR SUBSTITUTION ON THE FLORAL ODOR OF TETRAHYDROPYRANYLAND TETRAHYDROFURANYL ETHERS

Sulfur-containing analogues of tetrahydropyranyl and tetrahydrofuranyl derivatives of selected alcohols and phenols have been prepared and t heir odor properties evaluated. The compounds include derivatives in w hich either one or both of the oxygen atoms had been replaced with sul fur. Derivatives with two sulfur atoms do not exhibit pleasant odors; those with an endocyclic oxygen and an exocyclic sulfur generally exhi bit green notes. The floral character is found only in a few derivativ es with an endocyclic sulfur and an exocyclic oxygen.
