Z Carvone

The carvone was distilled before use b.p. 105-106° (14 mm.). The checkers used Z-carvone obtained from Shiono KoryoK.K. (Japan). [Pg.64]

An alternative route to Z-(-)-carvone (20) was developed from the more abundant (-)-a-pinene (2), albeit a somewhat lower overall yield (Scheme 5.7).36 The process involves hydroboration of 2 followed by oxidation of the resultant alcohol. Subsequent treatment of the /-isopinocamphone... [Pg.64]

Both enantiomeric forms of carvone are readily available. /-(-)-Carvone (20) is the major constituent of spearmint oil from Mentha spicata, whereas 6/-(+)-car-vone is a major constituent of caraway oil from the fruit of Carum cami or dill from the fruit of Anethum graveolens. t/Z-Carvone is found in gingergrass oils. [Pg.89]

Anethole, anisaldehyde, and myristicin (in aniseed), along with z/-carvone (present in P. anisum plant), have shown mild insecticidal properties. In houseflies, the major (56% by weight) active insecticide in the oil from anise tops was shown to be frans-anethole. Anisaldehyde and anethole increased the toxicity to houseflies when applied at the same as various common insecticides. Anethole also inhibits growth of mycotoxin-producing Aspergillus species in culture. ... [Pg.37]

Prins-pinacol condensation of a (Z)-a,p-unsaturated aldehdye and an (S)-carvone-derived alkynyl dienyl diol as illustrated below provided the formyl tetrahydroisobenzofuran as a single diastereomer in 84% yield in two steps <03JA6650>. [Pg.174]

Eight kinds of 8 hydroj dihydrocarveols (50a-d and 50a -d 8-p-menthane-2,8-diols) were obtained from carvone (93 and 93 ), dihydrocarvones (101a b and lOla -b ), and dihydrocarveols (102a d, 102a d ) by E. gracilis Z. as shown in Figure 19.99 (Noma et al., 1993). [Pg.808]
