## Abstract The importance of the β‐lactam substructure is exemplified by the several classes of β‐lactam antibiotics. Among the synthetic routes available to obtain this interesting scaffold, the Kinugasa reaction is a convergent strategy. In this article, the synthesis of a variety of chiral β‐la
