Chiral monoterpenoids

Other interesting examples of asymmetric syntheses involving chiral monoterpenoids include the Claisen reaction between (—)-menthyl phenylacetate and benz-aldehyde (optical purity is confirmed by microcalorimetry), a highly enan-tioselective carbenoid cyclopropanation catalysed by (4), ° and the crossed aldol... [Pg.7]

CHIRAL MONOTERPENOIDS IN PLANTS -ENANTIOSELECTIVE CHROMATOGRAPHIC ANALYSIS, AND THEIR BIOACTIVITY... [Pg.361]

In this article the gas-chromatographic methods adequate for an analysis of chiral monoterpenoids are presented. Recent results on the enantiomeric composition of monoterpenoids from different species of plants are discussed. The bioactivity of selected chiral monoterpenoids is also described. [Pg.361]

Linalool and linalyl acetate are the intensively studied chiral monoterpenoids. Their enantiomeric ratio had been investigated in the precious bergamot oil [36-38], lavender oils [39], and many other plants used as fragrance and flavour materials mainly fi-om Labiatae and Rutaceae families [40-42]. [Pg.374]

Investigations on authentic essential oils of Lavandula species are summarized in Table 6.20, detecting the chiral monoterpenoids with high enantiomeric purities as characteristic constituents of genuine lavender oils Besides R-linalyl acetate (11) and R-linalool (17), the chiral main compounds of genuine lavender oils 2R-trans-(2), 2R-cis-(3)-linalool oxide (fur.), (R)-lavandulol (13), as well as S-terpinen-4-ol (16) are detected [111]. [Pg.682]

Further examples of asymmetric reactions involving chiral monoterpenoids include the formation of chiral /S-keto-sulphoxides from (-)-menthyl carboxy-lates, " synthesis of diastereomeric tetrahedral molybdenum complexes,the enantioselective hydrosilylation of ketones,and the preparation of the chiral l-amino-2-phenylethylphosphonic acids. [Pg.15]
