Homonuclear 1 H COSY, long‐range COSY and relay coherence transfer (RCT) correlation spectroscopy NMR experiments were used together with fixed‐evolution HETCOR and selective INEPT spectra for complete 13 C and 1 H spectral peak assignments for tatsidine. Stereochemical and conformational assignments were made from the two‐dimensional NOE spectrum. The results of these studies confirmed the location of the methylenedioxy group at C‐7/C‐8.
