Titanium‐Mediated Oxidative Arylation of Homoallylic Alcohols

Angewandte Chemie International Edition, 2011
The addition of aryl groups to unactivated olefins represents a direct approach to C!C bond construction. Pd-catalyzed coupling of aryl halides with alkenes, the Heck reaction, offers a viable approach to arylation. However, terminal unactivated olefins often display low reactivity in Heck reactions and can yield mixtures of styrenes and allyl arenes ...

Addition of organocerium reagents to homoallyl alcohols

Tetrahedron Letters, 2001
Abstract Alkylcerium reagents and hydride ions add to multiple bonds of homoallyl alcohols under mild conditions, leading to saturated alcohols in good yields.

Synthesis of homoallylic alcohols in aqueous media

The Journal of Organic Chemistry, 1989
The reaction of aldehydes or ketones with allyl halides/Zn takes place readily in aqueous NH{sub 4}Cl solution in the presence of C-18 silica as a solid organic cosolvent. This efficient and high-yield reaction parallels the Grignard reaction in terms of stereo- and regioselectivity.

Radical cyclizations of bromo ketals from decalin homoallylic and bis-homoallylic alcohols

Tetrahedron Letters, 2001
Abstract The radical cyclizations of bromo ketals derived from the Birch-alkylation products of α-tetralones are described. The carboncarbon bond formation proceeds in a regio- and stereoselective way. The intra- and intermolecular trapping behavior was also explored.

Copper‐Catalyzed Trifluoromethylation of Trisubstituted Allylic and Homoallylic Alcohols

Chemistry – A European Journal, 2015
AbstractAn efficient copper‐catalyzed trifluoromethylation of trisubstituted allylic and homoallylic alcohols with Togni’s reagent has been developed. This strategy, accompanied by a double‐bond migration, leads to various branched CF3‐substituted alcohols by using readily available trisubstituted cyclic/acyclic alcohols as substrates.

Triethylborane Induced Intramolecular Hydrogermylation of Homoallylic Alcohols and Homopropargylic Alcohols

Chemistry Letters, 1993
Abstract Whereas platinum-catalyzed hydrogermylation of 3-hexenoxydipropylgermane provided five-membered ring product (5-propyl-1-germa-2-oxacyclopentane) as a main product, triethylborane induced radical cyclization gave six-membered ring product (6-ethyl-1-germa-2-oxacyclohexane) selectively.
