their corresponding acid chlorides and triethylamine, to produce homochiral cis-3-alkoxy-4-(1-aminoalkyl) β-lactams with virtually complete control of diastereoselectivity. In a similar manner, the reaction of phthalimidoacetyl chloride with these imines in the presence of triethylamine afforded the corresponding 3-phthalimido β-lactams as single diastereomers
