✦ Synopsis


Mechanistic and Synthetic Aspects of Stereoselective Reactions of Lithium Derivatives of Chiral Phosphine Oxides: X-Ray Crystal Structure of (1R*,2S*,1'S*,2'R*)-1-(1'-Diphenylphosphinoyl-2'phenylpropyl) -2-phenylsulfanylcyclohexan-1-ol.

-Ongoing interest in the chemistry of the diphenylphosphinoyl group leads to the investigations of the title synthetic aspects. It is noteworthy that the reaction of (Ia) with benzaldehyde is completely non-selective. The usefulness of such a reaction is shown by the transformation to the alkene (XIII) with 1,4-disposed stereocenters. The relative stereochemistry of (XI) is determined by X-ray analysis. Mechanistical aspects are discussed in detail. - (GUEGUEN, C.; O'BRIEN,
