Synthesis and antibacterial activity of 4,7-dihydro-4-ethyl-7-oxothieno(3,2-b)pyridine-6-carboxylic acids

The synthesis of some new 4,7-dihydro-4-ethyl-7-oxothieno(3,2-b)pyridine-6-carboxylic acids with various substituents on position 2 is described. The evaluation of the anti-bacterial activity of some compounds shows an activity different to those of the thieno(2,3-b)pyridine series.
