supporting information; experimental part, p. 16330 - 16333 (2011/02/23)
We report a Rh-catalyzed, regio- and enantioselective intermolecular olefin hydroacylation under mild conditions. Hydroacylations between homoallylic sulfides, containing a substrate-bound directing group, and salicylaldehyde derivatives occur in the presence of a spiro-phosphoramidite ligand, (R)-SIPHOS-PE, to give α-branched ketones in >20:1 selectivity and up to 97% ee. Our conditions are also applicable to the asymmetric intermolecular hydroacylation of 1,2-disubstituted olefins.
Lewis acid-catalyzed coupling reactions of allylsilanes with tris(phenylchalcogeno)methane. Synthesis of homoallylchalcogenoacetals
Silveira, Claudio C.,Fiorin, Gustavo L.,Braga, Antonio L.

Reaction of allylsilanes with tris(phenylseleno)methane or tris(phenylthio)methane in the presence of a Lewis acid furnishes the corresponding homoallylchalcogenoacetals in moderate to good yields.
Generation, Some Synthetic Uses, and 1,2-Vinyl Rearrangements of Secondary and Tertiary Homoallyllithiums, Including Ring Contractions and A Ring Expansion. Remarkable Acceleration of the Rearrangement by an Oxyanionic Group

A very general preparative method for homoallyllithiums consists of reductive lithiation of homoallylithiums consists of reductive lithiation of homoallyl phenyl sulfides by lithium 4,4'-di-tert-butylbiphenylide.The sulfides can be prepared by a variety o
Phenylthio Migrations in Rearrangements of 2,2-Bisphenylthioethanols
Blatcher, Philip,Warren, Stuart
, p. 1055 - 1066 (2007/10/02)
Thionyl chloride causes rearrangement of the title compounds to give 2,3-bisphenylthiopropenes (12) by a phenylthio shift.The products undergo phenylthio shifts on exposure to light.Some applications to synthesis are described.
