dc.descriptionThe 13C NMR spectra of some isoquinoline and tetrahydroisoquinoline alkaloids and their corresponding N-methosalts and of the bisbenzylisoquinoline alkaloid isochondodendrine were recorded and the signals assigned. The substituent shielding effects and the 13C1H long range couplings were analysed and utilized in the spectral interpretation. © 1978.

dc.descriptionThe fine structure of C7|3 3J(C7-H5) = 7.4 Hz| of 17, which becomes a multiplet in 18 and again a doublet | 3J(C7-H5) = 8.0 Hz | in 19, confirms the previous assignment. Methylation of 17 produces a crowded system in which the o-methyl group of C7 resonates, as expected, at lower fieldGaleffi, Marini-Bettolo, Vecchi, (1975) Gazz. Chim. Ital., 105, p. 1207
