The asymmetric ene reaction of prochiral aldehydes with alkenes has been effected by chiral organoaluminium reagent providing optically active homoallylic alcohols in both enantiomeric forms with high enantiomeric purity.
Highly stereoselective syntheses of alkenylsilanes and germanes utilizing cyclobutyl ketones

(E)-Alkenylsilanes were synthesized with high stereoselectivity by the diastereoselective addition of the dimethylphenylsilyllithium to the trans-2-phenylthiocyclobutyl ketones and the Lewis acid-promoted promoted stereospecific ring opening reactions of the resulting cyclobutanemethanol derivatives. (E)-1,5-Disubstituted 1,5-dienylsilanes and germanes were also produced stereoselectively by the similar zinc salt-catalyzed ring opening reaction of α-dimethylphenylsilyl- or α-triethylgermyl-1-[2-(trimethylsilylmethyl)cyclobutane]methanol derivatives.
Reductive α-substitution of sulfoxides with grignard reagents promoted by a magnesium amide

The reactions of sulfoxides bearing α-hydrogen(s) (RSOCHR1R2: R-alkyl or aryl; R1, R2 = H, alkyl, or aryl) with Grignard reagents (R3MgBr: R3 = Et, Ph, or vinyl) in the presence of the diisopropylaminomagnesium reagent, generated in situ by the treatment of diisopropylamine with the appropriate Grignard reagents in diethyl ether, have resulted in the formation of the corresponding sulfides (RSCR1R2R3) in moderate to good isolated yields.
