A concise stereoselective approach to β-Alkylaspartates from β-Lactams via [2 + 2] cycloaddition reaction of ketenes to glyoxylic ester-derived imines

syn β-Alkyl aspartates were obtained with high stereoselectivities from cis 4-alkoxycarbonyl-β-lactams prepared via [2 + 2] cycloaddition reaction of monoalkylketenes and glyoxalate derived imines.
