Terpenyl alcohols

Esters are widespread in fruits and especially those with a relatively low molecular weight usually impart a characteristic fruity note to many foods, e.g. fermented beverages [49]. From the industrial viewpoint, esterases and lipases play an important role in synthetic chemistry, especially for stereoselective ester formations and kinetic resolutions of racemic alcohols [78]. These enzymes are very often easily available as cheap bulk reagents and usually remain active in organic reaction media. Therefore they are the preferred biocatalysts for the production of natural flavour esters, e.g. from short-chain aliphatic and terpenyl alcohols [7, 8], but also to provide enantiopure novel flavour and fragrance compounds for analytical and sensory evaluation purposes [12]. Enantioselectivity is an impor-... 

This chapter reviews our study of Morita-Baylis-Hillman (MBH) and vinylmel ation reactions for the synthesis of achiral and chiral, functionalized, fluorinated allyl alcohols. Vinylmetalation of fluoro-carbonyls with aluminum and copper reajgents for the synthesis of unsubstituted, and p-substituted fluorinated allyl alcohols is summarized. An exploratory study of terpenyl alcohols as chiral auxiliaries in these reactions is also discussed.

Kinetic resolution of vinylic epoxides by the reduction with terpenyl dialkylboranes of high optical purity is a simple and direct method for the preparation of enantiomerically enriched epoxides. It allows for convenient configurational assignment of epoxides if the configuration of the corresponding allylic alcohol is known. Both enantiomers can be prepared using readily available enantiomeric diisopinocampheylboranes.
