Process for preparing (1R,2R)-2-(3-pyridyl)tetrahydrothiopyran-2-carbothioamide 1-oxides of general formula: ##STR1## (R.sub.1 =alkyl containing 1 to 4 carbon atoms), by the action of an alkyl isothiocyanate on the 1R,2R and 1R,2S sulphoxides of formulae: ##STR2## employed alone or mixed, the (1R,2R)-2-(3-pyridyl)tetrahydrothiopyran-2-carbothioamide 1-oxides thereby obtained and pharmaceutical compositions containing them. (1R,2R)-2-(3-Pyridyl)tetrahydrothiopyran-2-carbothioamide 1-oxides are especially useful as antihypertensives.
制备一般式为:##STR1##(其中R1=含1至4个碳原子的烷基)的(1R,2R)-2-(3-吡啶基)四氢噻吩-2-羧硫脲1-氧化物的过程,通过烷基异硫氰酸酯对式为:##STR2##的1R,2R和1R,2S亚磺酸盐的作用,单独或混合使用,从而获得(1R,2R)-2-(3-吡啶基)四氢噻吩-2-羧硫脲1-氧化物,并含有它们的药物组合物。(1R,2R)-2-(3-吡啶基)四氢噻吩-2-羧硫脲1-氧化物特别有用作为降压药。
