The addition of allylmagnesium chloride to the chiral, non-racemic α,β-epoxyimine (2) is highly diastereoselective, and the facial selectivity can be controlled by the use of BF 3 .OEt 2 ; Addition of vinylmagnesium bromide in the presence of this

Treatment of the α,β-epoxy-aldehydes (1) and (2) with Lewis acids followed by in situ reaction with carbon nucleophiles produces halohydrins of the products of “chelation controlled” addition to the aldehyde with high diastereoselectivity; The

The addition of methyl lithium, methyl magnesium halides, and allylstannanes to the α,β-epoxy-aldehydes (4) and (5) takes place with moderate to high stereoselectivity to give products which correspond to “non-chelation controlled” addition to
