Abstract
This article presents the structure elucidation of four new compounds, formed during the hemisynthetic preparation of trabectedin, an anti‐tumor natural product from Ecteinascidia turbinata. We report herein on the use of UV, MS and NMR spectroscopic data along with ^1^H and ^13^C spectral assignments obtained by means of 1D and 2D homo‐ and heteronuclear NMR techniques.

1 H and 13 C NMR spectral data for phytochelatin, NH 3 C --Glu-Cys 2 -Gly-COO , were assigned by a combination of one-( 1 H, 13 C) and two-dimensional (DQF-COSY, CH-COSY, HMBC) NMR experiments.
The indole alkaloid strychnobrasiline was studied using one-and two-dimensional NMR techniques. The interpretation of these spectra led to the complete assignments of all carbon and proton chemical shifts.
## Abstract The phytochemical investigation of carnauba wax led to the isolation of three new dammarane triterpenoids 1, 2 and 4, together with the known triterpene 3. The structures of the new compounds were determined by 1D and 2D NMR spectroscopy and by comparison with published data for closely
H and 13 C NMR spectroscopic data for 5a-androstanes and halo-5a-androstanes with different substituents at positions C-3, C-9, C-11 and C-17 were examined and assigned by a combination of 1D and 2D NMR experiments. The substituent effects on the 13 C chemical shifts were compared with those of epi-
## Abstract ^1^H and ^13^C NMR data for six pheno‐thiazine derivatives are reported. Spectral assignments were made on the basis of two‐dimensional homonuclear ^1^H,^1^H and heteronuclear ^1^H,^13^C correlation techniques (COSY, COSY‐LR, HETCOR, COLOC) and ^13^C,^1^H coupling constant measurements.
