(Chemical Equation Presented) A highly stereoselective synthesis of chiral α-amino-β-lactam through an ynamide-Kinugasa reaction is described. In addition, a mechanistic model is illustrated here to rationalize the observed diastereoselectivity, which depends on both the initial [3 + 2] cycloaddition step and the subsequent protonation for which both are highly selective.

The cycloaddition reaction of the Evans-Sjogren ketenes to imines, followed by α-hydroxylation of the resulting cycloadducts provides an efficient general asymmetric synthesis of α-keto β-lactams and derivatives.
