ABSTRACTConclusions1. On the basis of the results of a comparative study of the NMR spectra of dihydrogalanthamine and dihydroepigalanthamine and their acetyl derivatives it has been shown that in the hydrogenation of the C2-C3 double bond of galanthamine and its analog a diamagnetic shift of the i and C1-H protons by 0.35 and 0.25–0.60 ppm, respectively, take place.2. The anomalous nature of the CSs of theae C1-H protons in these compounds is due to the substantial influence on their magnetic anisotropy and electric field of the unshared pair of electrons of the O atom and the C-O bond of ring C.
