Chemical and spectral studies of lunarine (1) main alkaloid from Honesty, Lunaria biennis Moench, Crucifereae, have been completed. The stereochemistry of lunarinols I and II, obtained by reduction of the ketone function of lunarine, has been determined through a comparative study of the NMR spectra of their derivatives and of those of corresponding alcohols in the Pummerer's ketone series. Photoisomerization of the cinnamic system of ...
