Abstract

For sixteen compounds related to cryptopleurine the carbon-13 chemical shifts and some first-order coupling constants were measured. Excepting the case of very close signals (less than 0.3 ppm of separation) all the signals were assigned. For cis-stilbene and phenanthrene series some useful SCS for methoxy and carboxy groups were calculated.
