Ring transformation of 2-substituted isothiazol-3(2H)-ones to 3,4-dihydro-1,3-thiazin-4(2H)-ones by a novel carbene addition–ring expansion sequence

Wilfrid D. Crow,   Ian Gosney  and  Raymond A. Ormiston  

Abstract

Rhodium(II)-catalysed addition of diazo compounds to 2-substituted isothiazol-3(2H)-ones (1) results in a ready conversion into hitherto unknown 3,4-dihydro-1,3-thiazin-4(2H)-ones (2) in high yield.
