Highly Diastereoselective Synthetic Route to Enantiopure β<sup>2</sup>-Amino Acids and γ-Amino Alcohols Using a Fluorinated Oxazolidine (Fox) as Chiral Auxiliary
reactions of an amide enolate derived from a trifluoromethylated oxazolidine (Fox) chiral auxiliary occur with a complete diastereoselectivity and in good yields with various electrophiles. This reaction provides a versatile and straightforward strategy for the synthesis of β2-aminoacids and γ-amino alcohols in enantiopure form.
