isoborneol मीनिंग इन हिंदी

उदाहरण वाक्य

1. Hydrolysis into isoborneol followed by oxidation gives racemic camphor.
2. In another modification the catalyst is trimethylaluminium and the aldehyde 3-nitrobenzaldehyde is used as the oxidant, for example, in the oxidation of isoborneol to camphor.
3. For example, the key cyclization step in the total synthesis of ( R )-(-)-Muscone was an intramolecular asymmetric addition of a vinylzinc derivative to an aldehyde using a chiral amino-isoborneol ligand ( Figure " ( a ) Asymmetric addition of alkenylzinc to aldehyde in the total synthesis of muscone " ).
4. After transmetalation with diethylzinc, the generated alkenylzinc reagent ( C ) further reacted with the aldehyde ( D ) through exclusive addition to the ?-face under the control of (-)-3-exo-( dimethylamino ) isoborneol ( DAIB ) as a ligand ( Figure " ( b ) Detailed steps for the reaction " ).
5. Further research efforts of Pluh�r Zs . et al . on the volatile oil composition of " T . pannonicus " from nineteen different localities of Hungary, confirmed a significant essential oil polymorphism in this plant species, as twelve different chemovarieties were determined, namely : thymol, thymol / p-cymene, thymol / p-cymene / ?-terpinene, thymol / p-cymene / neral, thymol / p-cymene / ?-terpinene / ?-bisabolene, thymol / p-cymene / isoborneol / ?-terpinene, thymol / linalyl acetate / ?-terpinene / ?-cubebene, p-cymene / geraniol / linalyl acetate, linalyl acetate / geranyl acetate, germacrene-D / ?-caryophyllene, caryophyllene oxide / ?-cubebene / linalool, and germacrene-D / ?-caryophyllene / farnesol.
