A mild, highly regio-and stereoselective method for the crotylation of aldehydes and ketones mediated/catalyzed by titanocene(III) is described. Optimized conditions permit the selective generation of γ-adducts in high yields together with high stereoselectivity, with a predominance of anti stereoisomers.

Stereohomogeneus (E)- and (Z)-crotyltrifluorosilanes were prepared and used for the highly diastereoselective synthesis of threo- and erythro-β-methylhomoallyl alcohols, respectively, from aldehydes in the presence of fluoride ions.The mechanism of the reaction was discussed.
ALLYLIC ORGANOMETALLIC WAY TO CONTROL ACYCLIC STEREOCHEMISTRY AND ITS APPLICATION TO THE SYNTHESIS OF CARBOHYDRATES

The Cram/anti-Cram selectivity in the reactions of allylmetals with aldehydes and the erythro/threo selectivity in the reactions of substituted allylic organometallic compounds with other aldehydes can be controlled by the metal (M).Based on both selectiv
