The selective isomerization of strained heterocyclic compounds is an important tool in organic synthesis. An unprecedented regioselective isomerization of 2,2-disubstituted oxetanes into homoallylic alcohols is described. The use of tris(pentafluorophenyl

A highly enantioselective Cu-catalyzed borylation of 2-substituted 1,3-dienes is reported. The use of a chiral phosphanamine ligand is essential in achieving high chemo-, regio-, diastereo- and enantioselectivity. It provides access to a variety of homoallylic boronates in consistently high yield and enantiomeric excess with 2-aryl and 2-heteroaryl 1,3-dienes as well as sterically demanding 2-alkyl 1,3-dienes. Preliminary investigations based on a non-linear effect study point to a mechanism involving more than one metal center.
Regioselective Heck arylation of unsaturated alcohols by palladium catalysis in ionic liquid

, p. 3591 - 3593 (2008/09/20)
In contrast to almost all of the known examples of Heck arylation of unsaturated alcohols, which yield predominately β-arylated products, arylation under the Pd-DPPP catalysis in ionic liquid leads preferentially to aryl substitution at the α carbon, prov
