Allylmagnesium Halides Do Not React Chemoselectively because Reaction Rates Approach the Diffusion Limit

Competition experiments demonstrate that additions of allylmagnesium halides to carbonyl compounds, unlike additions of other organomagnesium reagents, occur at rates approaching the diffusion rate limit. Whereas alkylmagnesium and alkyllithium reagents could differentiate between electronically or sterically different carbonyl compounds, allylmagnesium reagents reacted with most carbonyl compounds at similar rates. Even additions to esters occurred at rates competitive with additions to aldehydes. Only in the case of particularly sterically hindered substrates, such as those bearing tertiary alkyl groups, were additions slower.
Use of cis-dichloro[(S)-α-methylbenzylamine](ethylene)Pt(II) as a chiral derivatizing agent for the determination by 195Pt-NMR of the enantiomeric composition of unsaturated ethers or alcohols having a quaternary chiral carbon atom

cis-Dichloro[(S)-α-methylbenzylamine](ethylene)platinum(II) is an efficient chiral derivatizing agent for the determination, by 195Pt-NMR spectroscopy, of the enantiomeric composition of unsaturated ethers and alcohols having a quaternary chiral carbon atom.
Novel N-substituted alpha aminoacid amides as calcium channel modulators

, (2008/06/13)
The compounds of formula I and derivatives thereof have been found to be active in tests that show modulation of voltage-dependent calcium channels, and are thus indicated for use in the treatment of diseases in which such modulation is beneficial, in par
