The new chiral thiophene 3 was prepared from (+)-nopinone via a de novo construction of the thiophene nucleus. From compound 3 four new S,S- and N,S-ligands, namely the C1-symmetric 2-(thiophen-2-yl)pyridine 7 and the C2-symmetric 2,2-bithiophene 5, 2,6-di(thiophen-2-yl)pyridine 8, and 2,6-di(thiophen-2-yl)thiophene 9 were synthesized.
