    摘要: The invention is concerned with the 7R/7S-diastereoisomer mixture of the formula ##STR1## in pure form, essentially free of the corresponding (4R)-isomers. The invention also concerns the 2R/2S-diastereoisomer mixture of the formula ##STR2## in pure form which is useful as an intermediate for producing I. In addition, the invention concerns a process for obtaining I by subjecting II to isochromane ring closure. Odorant compositions containing I and the use of I as an odorant are also described.

    摘要: A method of encapsulating an amphiphilic flavor or fragrance compound into a microcapsule having a hydrogel shell and an oil core. The flavor or fragrance compound is transported into and solubilized in the core by partition coefficient equilibrium using water in the capsule wall to transport the compound into the core. Microcapsules made by the method of the invention may have a wall thickness and contain a high concentration of the flavor or fragrance compound that has not previously been feasible.
