The 1H NMR parameters of the NCH2O protons in the spectrum of perhydropyrrolooxazine show its existence in solution at room temperature in the O-inside cis-fused conformation, rel-(3aS,6aS,6bR,10aS,11aS)6a-Methylperhydroindolobenzoxazine and rel-(3aS,6aS,6bS,10aR,11aS)-6a-methylperhydroindolobenzoxazine are shohn to adopt cis- and trans-fused conformations, respectively, for the corresponding bicyclic moiety.
