Abstract
magnified image The synthesis of 9‐amino‐5,6,7,8‐tetrahydrothieno[3,2‐b]quinoline (3) and 9‐amino‐5,6,7,8‐tetrahydrothieno[3,2‐b]quinolin‐5‐ol derivatives (4a, 4b, 4c, 4d, 4e, 4f, 4g) in good yield by three‐step procedures starting from 3‐aminothiophene‐2‐carbonitrile and 5‐substituted cyclohexane‐1,3‐dione is described.
