Abstract

Complete ^1^H and ^13^C spectral assignments are reported for peridinin, the major dinoflagellate carotenoid responsible for β€˜red tides’ in the ocean. These assignments were made with the aid of HETCOR, FLOCK and COSY 2D spectra and NOE difference spectra.

The rare alkaloid casimiroedine and its peracetylated derivative both show complex 1 H and 13 C spectra with almost all signals doubled owing to slow rotation about the amide bond. Nevertheless, it is possible, using 2D NMR methods, to assign fully the 1 H and 13 C spectra of the major and minor con

## Abstract Isocatalpanol and tecomaquinone I were obtained from roots of __Lippia sidoides__, a medicinal plant from northeast Brazil. Reduction of tecomaquinone I with NaBH~4~ yielded a new derivative. Structural elucidation was done on the basis of spectral data, mainly by high‐field NMR and ele
