Abstract:Thiophene as a Structural Element of Physiologically Active Compounds, VI: The Synthesis of cis- and trans-Octahydrothieno[2,3-c]quinolines . Two methods are described for the preparation of 3 , which is the key starting material for the synthesis of the title compounds 15 and 16 . Compound 12 is reduced to the diastereomeric amines 13 and 14 , which are subjected to the Pictet-Spengler reaction to yield compounds 15a and 16a . Both enantiomers of 15a were isolated.
