Reaction of the β-lactam-based oxazolidinone 5 with N-sulfonylimines provides the exo and endo azapenams 8 in 22-54% yield. The reactivity of 2H-azirines as 1,3-dipolarophiles towards β-lactam-based azomethine ylides derived from oxazolidinones 5 and 15 h

The Rh(ii)-catalyzed formal [3+2] and [3+3] cycloadditions of 1-tosyl 1,2,3-triazoles with 2H-azirines have been developed, which enable the efficient synthesis of polysubstituted 3-aminopyrroles and 1,2-dihydropyrazines, respectively. The reported [3+2] cycloaddition represents the first application of 1-sulfonyl 1,2,3-triazole as a [2C]-component in relevant cycloaddition reactions. This journal is
