Shimizu, Isao,Sakamoto, Toshiaki,Kawaragi, Saeko,Maruyama, Yooichiro,Yamamoto, Akio
, p. 137 - 138 (1997)
A novel method to substitute aromatic compounds with allylic groups using oxygen-containing allylic compounds in the presence of molybdenum or tungsten carbonyls under neutral conditions has been developed. The method is applicable to one step synthesis of methyl eugenol.

Thermal behavior of pinan-2-ol and linalool
Leiner, Janne,Stolle, Achim,Ondruschka, Bernd,Netscher, Thomas,Bonrath, Werner
, p. 8358 - 8375 (2013)
Linalool is an important intermediate for syntheses of isoprenoid fragrance compounds and vitamins A and E. One process option for its production is the thermal gas-phase isomerization of cis- and trans-pinan-2-ol. Investigations of this reaction were performed in a flow-type apparatus in a temperature range from 350-600 °C and a residence time range of 0.6-0.8 s. Rearrangement of the bicyclic alcohol led to linalool, plinols arising from consecutive reactions of linalool and other side products. Effects of residence time, temperature, surface-to-volume-ratio, carrier gas, and the presence of additives on yield and selectivity were studied. Furthermore, the effects of such parameters on ene-cyclization of linalool affording plinols were investigated. Results indicate that manipulation of the reaction in order to affect selectivity is difficult due to the large free path length to other molecules in the gas phase. However, conditions have been identified allowing one to increase the selectivity and the yield of linalool throughout pyrolysis of pinan-2-ol.

A donor-acceptor complex enables the synthesis of: E -olefins from alcohols, amines and carboxylic acids

Olefins are prevalent substrates and functionalities. The synthesis of olefins from readily available starting materials such as alcohols, amines and carboxylic acids is of great significance to address the sustainability concerns in organic synthesis. Metallaphotoredox-catalyzed defunctionalizations were reported to achieve such transformations under mild conditions. However, all these valuable strategies require a transition metal catalyst, a ligand or an expensive photocatalyst, with the challenges of controlling the region- and stereoselectivities remaining. Herein, we present a fundamentally distinct strategy enabled by electron donor-acceptor (EDA) complexes, for the selective synthesis of olefins from these simple and easily available starting materials. The conversions took place via photoactivation of the EDA complexes of the activated substrates with alkali salts, followed by hydrogen atom elimination from in situ generated alkyl radicals. This method is operationally simple and straightforward and free of photocatalysts and transition-metals, and shows high regio- and stereoselectivities.

Paragraph 0045; 0048, (2020/08/06)
The invention relates to a method for synthesizing high-purity 13C2-myrcene from 13C2-geraniol. The method comprises the following steps: (1) dissolving 13C2-geraniol in an organic solvent, adding hydrogen peroxide and p-toluenesulfonic acid monohydrate, stirring for reaction, monitoring the reaction process by TLC (Thin Layer Chromatography), after the reaction is completed, concentrating the obtained reaction solution under reduced pressure, and purifying by silica gel column chromatography to obtain an intermediate, (2) dissolving the intermediate in an organic solvent, stirring and heatingto react with potassium tert-butoxide and 18-crown ether-6 dissolved in an organic solvent under the protection of nitrogen, by TLC, monitoring the reaction process, after the reaction is completed,stirring and cooling the obtained reaction liquid, adding diethyl ether for extraction, sequentially cleaning an organic phase with water, a saturated sodium bicarbonate aqueous solution and saturatededible salt water, carrying out drying, and carrying out silica gel column chromatography purification so that high-purity 13C2-myrcene is obtained. According to the method, no metal catalyst or additive is used, the process conditions are mild, and the method has the advantages of being simple, efficient, economical and environmentally friendly and is particularly suitable for synthesis of isotope 13C or 14C labeled myrcene and non-isotope labeled myrcene.
