Thioanalogs of Sparteine Lactams [6]. Part II. (+)-2-Thionosparteinium Perchlorate


(+)-2-Thionosparteinium perchlorate has been obtained and characterized by IR and NMR spectroscopy. On the basis of the coupling constant and chemical shifts for C(12) and C( 14) a boat conformation of ring C is proposed. The infrared spectrum in the solid state indicates an intermolecular hydrogen bond N+-H--S. This has been ascertained by X-ray crystal structure determination: H---S 2.44(8)A, N+---S 3.279(6)A, N+-H S 160(6)°. The solution NMR spectra clearly show that the solid state stucture is retained in solution.
