The studies that eventually led to the synthesis of 6 started by installation of one of the all-carbon stereocenters by addition of vinylmagne-sium bromide to the lithium enolate of (i )-carvone oxide 120. This reaction afforded compound 121 as a single isomer, albeit in only 30% isolated... [Pg.89]

The spiraled architecture of welwitindolinone A isonitrile 196 has inspired the development of a variety of strategies for its construction. A beautifully simple protecting group-free synthesis of (-F)-welwitindolinone A has been achieved by Baran and coworkers [115-117]. As depicted in Scheme 48, the key step for installation of the aU-carbon quaternary center at oxindole C3 involved fluoro-hydroxylation of (—)-fischerindole 1 194 via treatment with aqueous Xep2. The desired natural product, 196, was obtained as a single diastereomer in 44% yield. The origin of the asymmetry at oxindole C3 can be traced back to enantiopure carvone oxide. [Pg.426]

In orchids pollinated by five species of Eulaema and three species of Euglossa in Panama, carvone oxide (80) is the dominant volatile compound in 11 of 12 plants pollinated. Although 11 of these plants are orchids, Dalechampia spathulata (Euphorbiaceae) also produces carvone oxide and is pollinated by the same bees (Harbome, 1987, 1989). [Pg.344]

IFRA and RIFM have forbidden the use of several essential oils and components, including costus root oil, dihydrocoumarin, musk ambrette, and balsam of Peru (Ford, 1991) a concentration limit is imposed on the use of isoeugenol, cold pressed lemon oil, bergamot oil, angelica root oil, cassia oU, cinnamic alcohol, hydroj citronellal, and oakmoss absolute. Cinnamic aldehyde, citral, and carvone oxide can only be used with a quenching agent. [Pg.638]
