Biosynthesis of monoterpenes. Stereochemistry of the enzymatic cyclizations of geranyl pyrophosphate to (+)-alpha-pinene and (-)-beta-pinene.
The conversion of geranyl pyrophosphate to (+)-alpha-pinene and to (-)-beta-pinene is considered to proceed by the initial isomerization of the substrate to (-)-(3R)- and to (+)-(3S)-linalyl pyrophosphate, respectively, and the subsequent cyclization of the anti, endo-conformer of these bound intermediates by mirror-image sequences which should result in the net retention of configuration at C1...
متن کاملFacile syntheses of monodisperse ultrasmall Au clusters.
During our effort to synthesize the tetrahedral Au20 cluster, we found a facile synthetic route to prepare monodisperse suspensions of ultrasmall Au clusters AuN (N < 12) using diphosphine ligands. In our monophasic and single-pot synthesis, a Au precursor ClAu(I)PPh3 (Ph = phenyl) and a bidentate phosphine ligand P(Ph)2(CH2)(M)P(Ph)2 are dissolved in an organic solvent. Au(I) is reduced slowly...
متن کاملAnalgesic effects of alpha-pinene on pain models of writing and plantar tests in rats
Background: The aim of this study was to evaluate the analgesic effects of Alpha Pinene in writing and plantar pain tests in rats. Methods: This study was performed on male Wistar rats. Group 1: Normal saline was administered intraperitoneally (IP). Group 2: Diclofenac sodium at a dose of 5 mg/kg was administered (IP). Group 3: Alpha Pinene was administered (IP) at a dose of 0.1 mg/kg. Group ...
متن کاملLaser Raman spectroscopic study of specifically deuterated phospholipid bilayers.
Raman spectra of 1,2-dimyristoyl-sn-glycero-3-phosphocholines specifically deuterated in the 2 chain at one of positions 3, 4, 6, 10, 12, and 14 have been obtained as a function of temperature. The frequencies of the CD2 vibrational stretching modes depend on the position of the labeled CD2 group, being maximum at position 3 of the acyl chain and then decreasing until they become constant beyon...
متن کاملFacile syntheses of (+)-gabosines A, D, and E.
(+)-Gabosines A (12), D (4), and E (5), which share the same trihydroxycyclohexenone skeleton, were synthesized from enone 11 as the common intermediate. The key building block 11 was accessed by an intramolecular aldol cyclization of a diketone derived from D-glucose (8).
