    • The present invention provides a method of preparing thieno[3,2-c]pyridine derivatives of formula I: ##STR1## wherein R.sub.1 is selected from the group consisting of lower alkyl; lower alkylene phenyl; substituted lower alkylene phenyl wherein the phenyl is substituted from 1 to 3 times with lower alkyl, lower alkoxy, lower acyloxy, hydroxy, nitro and halo; lower alkylene naphthyl, lower alkylene thienyl; lower alkylene diphenyl; lower alkylene-hydroxy-phenyl; substituted lower alkylene-hydroxy-phenyl wherein the phenyl is substituted from 1 to 3 times with lower alkyl, lower alkoxy, lower acyloxy, hydroxy, nitro, and halo; lower alkylene-hydroxy-naphthyl; lower alkylene-hydroxy-thienyl; lower alkylene-hydroxy-diphenyl, and R.sub.2 is H or lower alkylene. The method comprises reacting a compound of a formula II: ##STR2## with a cyclic dioxy or cyclic dithio in the presence of catalyst.
    • 本发明提供制备式I的噻吩并[3,2-c]吡啶衍生物的方法:其中R 1选自低级烷基; 低级亚烷基苯基; 取代的低级亚烷基苯基,其中苯基与低级烷基,低级烷氧基,低级酰氧基,羟基,硝基和卤素取代1至3倍; 低级亚烷基萘基,低级亚烷基噻吩基; 低级亚烷基二苯基; 低级亚烷基 - 羟基苯基; 取代的低级亚烷基 - 羟基 - 苯基,其中苯基与低级烷基,低级烷氧基,低级酰氧基,羟基,硝基和卤素取代1〜3倍。 低级亚烷基 - 羟基 - 萘基; 低级亚烷基 - 羟基 - 噻吩基; 低级亚烷基 - 羟基 - 二苯基,R 2为H或低级亚烷基。 该方法包括在催化剂存在下使式II化合物与环状二氧基或环状二硫基反应。
