Syntheses of Sulfoxide Derivatives in the Benzodiazine Series. Diazines. Part 37.
Various benzodiazine sulfoxides are prepared via an efficient aromatic substitution
51- 124 —
reaction of the corresponding halobenzodiazines with lithiated thiolates. Alkyl and arylsulfanylbenzodiazines are obtained, which are converted by oxidation with MCPBA
into the desired sulfoxides. In addition, an improved one-pot synthesis for sulfoxide
(XIV) is presented (to be continued). — (LE FUR, N.; MOJOVIC*, L.; TURCK, A.;
