Synthesis and Reactivity of 4-Substituted-2,3-dihydrobenzo-1,4-thiazines
A series of derivatives of 4H-2,3-dihydrobenzo-1,4-thiazine has been prepared. 4-Acetyl-2,3-dihydrobenzo-1,4-thiazine undergoes self-condensation by n-butylmagnesium bromide affording the corresponding 4-acetoacetyl-2,3-dihydrobenzo-1,4-thiazine, which, is converted to 5H-1,4-thiazino<2,3,4-ij>quinolin-5-one.Halogenation of the acetyl derivative takes place at the position 2 of the heterocyclic ring and oxidation leads to 1-oxides and 1,1-dioxides.
