Selective Asymmetric Dihyroxylation of Polyenes
Becker, Heinrich,Soler, Marcos A.,Sharpless, K. Barry
, p. 1345 - 1376 (2007/10/02)
The asymmetric dihydroxylation procedure (AD) is applied to a variety of polyenes.In many cases excellent regioselectivities are obtained.The observed selectivities are rationalized in terms of electronic and/or steric inherent to the substrate, superimposed on the substrate's favorable or unfavorable interactions with the binding pocket of the AD ligand.Surprisingly, for medium and large ring olefins with trans-double bonds outstanding enantioselectivities are realized using the pyrimidine ligands.A hexaol of D3 symmetry is prepared from all trans cyclodecatriene.

A synthesis of monocyclic monoterpenes: p-mentha-1,8-dien-4-ol (1), terpinolene (4) and p,α-dimethylstyrene (5) from the titled compound 7, as a common precursor, is reported.
LEWIS ACID CATALYSED PINACOL REARRANGEMENT - A SHORT SYNTHESIS OF KARAHANAENONE
Bhushan, Vidya,Chandrasekaran, Srinivasan
, p. 1537 - 1538 (2007/10/02)
The pinacolic coupling reaction has been effectively used to prepare the unsymmetrical pinacol 2 and this key intermediate underwent a smooth ring enlargement to the monoterpene karahanaenone 3, an odoriferous constituent of Japanese hop and Cypress oil.
