• 개요

  A second macrocyclic alkaloid found in Euonymus sieboldiana Blume, this base also crystallizes as colourless crystals and is best purified by recrystallization from EtOH. It is dextrorotatory having [α]_D + 24.9° (c 1.27, CHCI3). The ultraviolet spectrum is very similar to that of the preceding alkaloid with absorp_x0002_tion maxima at 224 and 26S mJi. The structure, as determined from the NMR and mass spectra is virtually identical with that of neoeuonymine, the only difference being the replacement of an acetoxy group with a ketone group in the reduced naphthalene moiety.
