Proton magnetic resonance studies of compounds with bridgehead nitrogen atoms—IV : Configurational and conformational studies with methyl substituted 8-thia-1-azabicyclo [4.3.0] nonanes

Abstract

The preferred conformations of a series of Me substituted 8-thia-1-azabicyclo[4.3.0]nonanes have been assigned on the basis of the 2700–2850 cm −1 region of the IR spectra and on the geminal coupling constants of the NCH 2S protons.
