The asymmetric addition of methane- and p-toluenesulfonyl chloride to 1-phenylpropene catalyzed by Ru2Cl43 affords optically active 1:1 adducts, (+)-(1R,2RS)-1-chloro-2-methylsulfonyl-1-phenylpropane (2) and (+)-(1R,2RS)-1-chloro-1-phenyl-2-tosy

Hydride reductions of oxime ethers to hydroxylamine derivatives are facilitated by the participation of neighboring hydroxyl groups. Precomplexation with zirconium cation in ether-methylene chloride solutions is effective for selective C=N bond reduction. The course for stereochemical control is dictated by Lewis acid coordination complexes of E- and Z-oximino ethers which lead to the preferred diastereofacial delivery of external hydride.

High enantioselectivity (up to 97percentee) have been achieved in the protonation of samarium enolates which were generated by SmI2-mediated cross-coupling reaction between unsymmetrical dialkylketene and allyl iodide, using, using a C2-symmetr
