Analysis of volatile components in juniper oil by high resolution gas chromatography and combined gas chromatography/mass spectrometry: Analysis of volatile components in juniper oil by high resolution gas chromatography and combined gas chromatography/mass spectrometry. Bonaga, Giorgio; Galletti, Guido C. (Dip. Protez. Valorizzaz. Agroalimentare, Univ. Bologna, Bologna 40126, Italy). Ann. Chim. (Rome), 75(3-4), 131-6 (English) 1985. CODEN: ANCRAI. ISSN: 0003-4592. DOCUMENT TYPE: Journal CA Section: 62 (Essential Oils and Cosmetics) Gas chromatog. of juniper (Juniperus communis) oil showed at least 40 components (monoterpenes, and sesquiterpenes) identified by mass spectra. The largest fraction of the oil consisted of 10 monoterpene hydrocarbons (60.3%) of which a-pinene [80-56-8] (33.6%), b-myrcene [123-35-3] (11.0%), sabinene [3387-41-5] (7.6%), limonene [138-86-3] (3.1%) and b-pinene [127-91-3] (2.5%) were present in greater quantities. The minor monoterpenes were 4-thujanol [546-79-2] (0.9%), 4-terpinenol [562-74-3] (2.1%), a-terpineol [98-55-5] (0.2%), campholene aldehyde [4501-58-0] (0.2%), verbenone [80-57-9] (0.2%) and bornyl acetate [76-49-3] (0.4%). The latter 2 compds. were found for the 1st time in juniper oil.

Dehydration reactions of pinene glycols: Dehydration reactions of pinene glycols. I. Cis-pinane-trans-2,3-diol in the presence of p-toluenesulfonic acid or zinc bromide. De Pascual Teresa, J.; Sanchez Bellido, I.; Santos Barrueco, J. F. (Dep. Quim. Org., Fac. Cienc., Salamanca, Spain). An. Quim., 72(6), 560-4 (Spanish) 1976. CODEN: ANQUBU. DOCUMENT TYPE: Journal CA Section: 30 (Terpenoids) (-)-Cis-pinane-trans-2,3-diol (I), prepd. 4501-58-0 and 22339-21-5 are cas registry numbers of chemicals which are used as reagents here. by oxidn. of (-)-.alpha.-pinene and redn. of (+)-2-hydroxypinocamphone, was dehydrated with p-MeC6H4SO3H to (+)-pinol, (-)-isopinocamphone, and (+)-.alpha.-campholenealdehyde (II). II was the product of a Wagner-Meerwein rearrangement, followed by a bond cleavage. Dehydration of I with ZnBr2 also gave (-)-6-endo-bromoisoborneol. I 3-acetate underwent similar dehydration reactions, but not the bond cleavage reaction. .
