The 1 H (200 MHz) and 13 C (50.3 MHz) NMR spectra of some hexa‐ and octahydropyrazino[1′, 2′ : 1,2]pyrido‐[3,4‐ b ]indoles (1–13), 15‐azayohimbanes (15–18), and related compounds (14, 19, 20) are reported. The data have been analyzed in terms of the preferred conformation (9–13, 15–20) and configuration (15–20).
