Asymmetric metal carbene insertion into the Si---H bond
Tetrahedron Letters, Volume 35, Issue 26, 27 June 1994, Pages 4565-4568
Yannick Landais, Denis Planchenault

Graphical Abstract

α-Silyl-α-substituted acetic esters have been prepared in good yields and reasonable diastereoselectivities, using an asymmetric metal carbene insertion into the Si---H bond. Optically active 1,2-diols were then prepared after reduction of the ester and conversion of the C---Si bond into a C---OH bond.

Graphical abstract

Two pairs of novel diastereomeric cyclopalladated ferrocenylimines (SpSC)-3 and (RpSC)-4 with both planar and central chirality have been synthesized starting from inexpensive and readily available chiral β-amino alcohols. The two pairs of diastereomers were characterized by elemental analysis, IR, 1H NMR and specific rotations. Furthermore, the structures and absolute configurations of complexes (SpSC)-3a and (RpSC)-4b have been determined by single-crystal X-ray diffraction.
