  Efficiency of chirality transfer in anionic oxy-Cope rearrangement depends solely on the orientational preference of the oxyanionic bond in the substrates with a single carbinol carbon chiral center. In chairlike transition-state conformations for the rearrangement of simplest substrates like anions generated from (E)-1-phenyl-1,5-hexadien-3-ol and (E)-1,5-heptadien-4-ol, the oxyanionic bond is more prone to adopt the pseudoaxial orientation. On the other hand, anions generated from (E)-2-methyl-1,5-heptadien-4-ol, (E)-5-tert-butyl-1-phenyl-1,5-hexadien-3-ol, and 4-(2'-methyl-1'-cyclohexenyl)-1-buten-3-ol undergo rearrangement via chairlike transition states in which the pseudoequatorial oxyanionic bond is favored. It can thus be surmized that there is a slight stereoelectronic preference for the pseudoaxial oxyanionic bond in the chairlike transition states for the rearrangement of substrates without steric constraints. Substitution at C5 of the basic 1,5-hexadien-3-ol framework of substrates, however, leads to 1,3-diaxial steric interaction in the chairlike transition states with pseudoaxial oxyanionic bond, and pseudoequatorial disposition of oxyanionic bond becomes more favorable.

  The methanolic extract obtained from rose flowers was subjected to XAD-8 adsorption chromatography. Prefractionation of the methanolic eluate using multilayer coil countercurrent chromatography (MLCCC) yielded five subfractions. From the least polar subfraction V, a major amount of the key odorants of rose oil, that is, isomeric rose oxides 1a/b, was liberated upon heat treatment at pH 2.5. Further chromatographic workup of fraction V led, for the first time, to the identification of the genuine rose oxide precursor (S)-3,7-dimethyl-5-octene-1,7-diol (2). In addition to diol 2, the following monoterpene diols have been identified: 3,7-dimethyl-7-octene-1,6-diol (3), 2,6-dimethyl-1,7-octadiene-3,6-diol (4), (2E,5E)-3,7-dimethyl-2,5-octadiene-1,7-diol (5), (2E)-3,7-dimethyl-2,7octadiene-1,6-diol (6), (2Z,5E)-3,7-dimethyl-2,5-octadiene-1,7-diol (7), (2Z)-3,7-dimethyl-2,7-octadiene-1,6-diol (8), (Z)-2,6-dimethyl-2-octene-1,8-diol (9), (E)-2,6-dimethyl-2-octene-1,8-diol(10), (2)-2,6-dimethyl-2,7-octadiene-1 ,6-diol(ll), (E)-2,6-dimethyl-2,7-octadiene-1,6-diol (12), (2E,GE)-2,6-dimethyl-2 ,6-octadiene-1,8-diol(13), (2E,6Z)-2,6-dimethyl-2,6-octadiene-1,8-diol(14), 2,6-dimethyloctane-1,8-diol(15), 2,6-dimethyl-7-octene-1,6-diol (16), (E)-3,7-dimethyl-2-octene-1,8-diol (17), (Z)-3,7-dimethyl-2-octene-1,8-diol (18), 3,7-dimethyloctane-1,7-diol (19), 2,6-dimethyl-7-octene-2,6-diol (20), 3,7-dimethyl-6-octene-1,3-diol (21) and (2E)-3,7-dimethyl-2,6-octadiene-1,4-diol (22).
