- 論文の詳細を見る
In order to confirm the structure of natural capaurimine (I), 1,10-dihydroxy-2,3,11-trimethoxy-5,6,13,13a-tetrahydro-8H-dibenzo [a, g] quinolizine (IIa) was synthesized and its nuclear magnetic resonance spectrum was compared with that of capaurimine (I). The patterns of all the signals of the synthesized sample (IIa) were found to be similar to those of the natural one, but the τ values were different. Further, methylation of IIa with diazomethane afforded 1,2,3,10,11-pentamethoxy-5,6,13,13a-tetrahydro-8H-dibenzo [a, g]-quinolizine, which was identical with an authentic specimen in spectral characteristics.
