, p. 1773 - 1774 (1998)
A three-step sequence for the construction of the C-aromatic taxane nucleus from easily available A-ring unit 2 and C-aromatic unit 3 is reported; SnCl4 promoted reaction of 4, presumably via the diastereoselective oxonium ene cyclisation react

The regioselectivity of the recluctive opening of cyclopropylogous α- hydroxy carbonyl compounds using SmI2 in THF or THF-HMPA was studied and shown to depend strongly on the substrate. In some cases, a tandem cyclopropyl opening-deoxygenation reaction afforded the corresponding γ- keto alkenes in one step.
β-Pinene-6-one: A pivotal synthetic intermediate
Hebrault,Uguen
, p. 6699 - 6702 (2007/10/03)
Submitting the title ketone to either acetoxymercuration or basic conditions resulted in the formation of the acid β-5 and α-5, respectively, with an useful selectivity, related rearrangements being observed by using the corresponding alcohol and its epoxy derivative.
