strategy. In this article, the synthesis of a variety of chiralβ-lactams by the Kinugasa reaction between terminal alkynes and nitrones is described. These sugar-derivedβ-lactams were synthesized by the reaction between cyclic nitrones derived from different sugars, tartrate ester, and alkynes obtained from different sugars. The reaction gave moderate to good yields of β-lactams with high diastereoselectivity
