摘要

Tetrahydro-1,4-thiazine dioxide and its N-atom and/or C-atom substd. derivs. are prepd. by reaction of bis-(beta-hydroxyethyl)-sulphone, 1,4-thiazine-dioxide or their C-atom substd. derivs. with aromatic amino which have =1 aromatic gp. substd. by prim-amino gps. and at least in each case one amino gp. and/or hydrazine gp. substd. aliphatic, araliphatic, cycloaliphatic, hydrazine gp. substd. aromatic gp. and/or a hydrazine gp.
