Abstract

2-Cyano-substituted 1,4-benzothiazine 1,1-dioxides, required for antiviral studies, were prepared by a reductive cyclodehydration of an ortho-nitro sulfone precursor containing a pendant aryl ketone group. The ring-forming reaction also furnishes a non-cyclized benzamide as a major byproduct via an unexpected acyl transfer reaction.
