Abstract

The regio- and diastereoselectivity of the addition of PhCu, BF3 reagent on chiral acetals derived from several mono or dienic aldehydes was studied. It was found that monoethylenic acetals react regio- and diastereoselectively via an overall anti SN2' reaction. The regioselectivity observed with the dienic acetals seems to be strongly dependent on the nature of the acetal. In all cases the SN2" reaction was the result of an anti process.
