Myrtenol

The glucosides of menthol, citronellol, nerol, geraniol, cw-myrtenol, L-borneol, linalool and a-terpineol yielded yellow-green fluorescent chromatogram zones in long-wavelength UV light (2 = 365 nm). The same applied to arbutin (hRf 45 — 50). 

Myrtenol, CjpHjgO, is a primary cyclic alcohol, which was isolated from essential oil of myrtle, in which it occurs principally in the form of its acetic ester, by von Soden and Elze. It is separated from geraniol, with which it is found, by fractional distillation, and by the crystallisa-... 

Myrtenol forms an acetic ester, quantitatively, so that it can be determined by aeetylisation. 

On oxidation with chromic acid in acetic acid solution, myrtenol yields a corresponding aldehyde, which has been termed myrtenal. This body has the following characters —... 

Myrtenol, according to Semmler and Bartelt, has the following constitution —... 

Myrtenal, C oH, 0, is an aldehyde found in the oil of Perilla nankin-ensis, associated with perillic aldehyde. It is also formed by the reduction of myrtenol, an alcohol of the formula CjpH,gO, occurring in oil of myrtle leaves. Myrtenal has the following characters —...

Oxygenated monoterpenes which are found in almost every bark beetle species attacking coniferous trees, include czs-verbenol 246, frans-verbenol 247, and myrtenol 248, representing primary products of allylic oxidation of the host terpene a-pinene 45. Further oxidation of 247 or 248 leads to the... 

Manganese(lil) acetate oxidation of a-pinene yields two lactones analogous to those reported earlier with (+)-p-menth-l-ene however, the major product consists of derived acetates [of a-terpineol, c/5-pin-3-en-2-ol, and myrtenol (224 ... 

Further papers in this section include the hydrosilylation of a-pinene and of j8-pinene, ° thiocyanation and selenocyanation of a-pinene, ° cationic polymerization of a- and /3-pinene epoxides,bromination of ( )-c/s-pinonic acid with dioxan dibromide, and straightforward myrtenol (224 R=CH20H) ° and tetrahydroperillyl alcohol syntheses from -pinene epoxide.

Vollmann et.al reported the TLC determination of eugenol in mixtures containing bomeol, norphinon, and myrtenol as components of Geum urbanum [20]. The method uses silica gel as the stationary phase, and 3 1 pentane-ether as the mobile phase. Detection is effected on the basis of the UV absorbance at 366 nm, and by spraying with vanillin-sulfuric acid reagent and heating at 120°C for 10 minutes. 

In a second attempt, a whole range of bicyclic 7-spirolactones (synthesized from (+)- and (-)-limonene) as well as tricyclic 7-lactones with a pinane system (from (R)-(-)-myrtenol and (-)-a-pinene) were synthesized. In total, 13 semisynthetic compounds 74-86 were tested for their antifeedant activity against the three storage pests. Antifeedant activities of the semisynthetic compounds were generally not very high when tested against... 

The adsorptive separation of pinenes on Zeolites is reported.303 The C-6 and C-7 13C n.m.r. chemical shifts in bicyclo[3,l,l]heptanes support other known conformational evidence and confirm that cls-pinane and ds-myrtanol (209 X = OH) have a bridged-boat conformation, that trans-myrtanol has a bridged-chair conformation, and that trans-2-pinanol and myrtenol (210 X = OH) have Y-shaped conformations verbenone (211 R R2 = O), and trans-verbenol (211 R1 = H, R2 = OH) give anomalous results which may be due to a conjugation effect the bridged-chair... 

Synthetic routes to trans-verbanone are discussed,308 and mercuric acetate in boiling methanol converts /3-pinene into a 65 35 mixture of the myrtenol ether (212 R = Me) and the trans-pinocarveol ether (213 R = Me).309...
