Western Australian Sandalwood Oil—New Constituents ofSantalum spicatum(R. Br.) A. DC. (Santalaceae)

Sandalwood Fragrance Biosynthesis Involves Sesquiterpene Synthases of Both the Terpene Synthase (TPS)-a and TPS-b Subfamilies, including Santalene Synthases

“…Although conversion of GPP did occur, a linear relationship existed between substrate concentration and V 0 , even at high (Ͼ100 M) concentrations, rather than an asymptotic curve indicative of active site saturation. Monoterpenes have only been reported in sandalwood oil at very low concentrations (23,26).…”

“…Monoterpene identification was aided through an in-house standard collection. All mass spectra were compared with the NIST 2005 library and the literature (17)(18)(19)(20)(21)(22)(23). The Kovat retention indices (KIs) were determined for all compounds (supplemental Figs.…”

Synthesis and natural occurrence of (Z/E)-β-and γ-curcumen-12-ol

“…together with the corresponding 1,3-diene (Z)-2. 5 Both sesquiterpene alcohols (Z)-1 and (Z)-2 were also detected in East Indian (S. album L.) 6 and New Caledonian sandalwood oil (S. austrocaledonicum Vieill. var.…”

Crystal structure of (1R*,2S*,5S*,6S*,7R*)-6-(3,5-dinitrobenzoyloxy)methyl-2,7-dimethyl-tricyclo [5.2.2.01,5]undec-8-ene, C21H24N2O6

“…A. DC. (Santalaceae) [1]. It was isolated analogously to its enantiopure C-6-epimer (1R,2S,5S,6R,7R)-2,7-dimethyl-tricyclo[5.2.2.0 1,5 ] undec-8-en-6-carbaldehyde (II) [2].…”

“…The title compound is a derivative of the corresponding (1R*,2S*,5S*,6S*,7R*)-2,7-dimethyl-tricyclo[5.2.2.0 1,5 ]undec-8-en-6 carbaldehyde (I) formed by a two step procedure: a) reduction of aldehyde I with LiAlH 4 in Et2O and b) esterification of the crude alcohol with 3,5-dinitrobenzoyl chloride, triethylamine and a catalytic amount of 4-dimethylaminopyridine (DMAP) in CH 2Cl2. It was impossible to determine the absolute structure of the title compound, however, other derivatives of aldehyde I (p-bromobenzoate and p-bromosulfonate) could not be crystallized.…”
