Abstract

A Selective Synthesis of β-Isothiocyanato Ketones Through a Staudinger/Aza--Wittig Reaction of β-Azido Ketones. -Three β-isothiocyanato ketones (III) are synthesized by reaction of β-azido ketones and CS2. By reaction with ammonia or methylamine they can be transformed into the corresponding pyrimidinethiones of type (IV) or (VI). -(FESENKO, A. A.; DEM'YACHENKO, E. A.; FEDOROVA, G. A.; SHUTALEV*, A.
