Ibe, Kouta,Yamada, Takeshi,Okamoto, Sentaro
, p. 10188 - 10200 (2019/12/25)
Two novel 16-oxa-vitamin D3 analogues were synthesized using a tandem Ti(ii)-mediated enyne cyclization/Cu-catalyzed allylation, Ru-catalyzed ring-closing metathesis reaction, and a low-valent titanium (LVT)-mediated stereoselective radical red
Regio- and Stereo-selective Oxidation of gem-Dimethyl Olefins via -Sigmatropic Rearrangement of Allyl Amine Oxides

, p. 2035 - 2038 (2007/10/02)
Highly regio- and stereo-selective oxidation sequences are described for the efficient conversion of the gem-dimethyl olefin terminus of acyclic terpenes to terminal trans-allylic alcohols and trans α,β-unsaturated aldehydes.

The ring cleavage reactions of α-ethylenic epoxides by sodium phenoxide afforded a mixture of products.Problems of competitive attack by this nucleophile, at the less substituted carbon (compounds A) or at the β-ethylenic carbon atom (compounds B and C), were encountered and could be resolved by judicious choice of reaction conditions (solvents, stereochemistry of the oxiranes).The regioselectivity of the attack was dependent on the transition states, implying weak steric hindrance and a conjugation oxirane - double bond.
