A set of twenty one lycorenine derivatives has been prepared from the alkaloid hippeastrine (1). The modifications performed on hippeastrine included some functional group transformations, structural simplification and preparation of dimers. All alkaloids were tested as potential antimalarial agents, being the hippeastrine dimers the most active compounds.

Provided are compounds and compositions for prevention and/or elimination of Zika virus infection. Also provided are methods for preventing and treating a subject in need of prevention or treatment of Zika virus.
evidence for the assigned structure is presented from the results of the study of the Von Braun reaction on clivonine and some of its derivatives. A simple sequence of reactions which involves the conversion of clivonine to the known lactone alkaloid 8 by treatment the chlorolactone 16 with base then acid is described. This conversion substantiates the relative stereochemistry provided by the PMR spectral
