Bridgehead nitrogen heterocycles 3a , b and 6a , b containing the thieno‐pyrimidine system have been prepared from the versatile intermediates 3‐amino‐2,3‐dihydro‐5,6‐dimethyl‐2‐thioxo‐thieno[2,3‐ d ]pyrimidin‐4‐(1 H )‐one 1 and its hydrazinium or potassium salts 4 ; their structural elucidation is also reported.
