Studies in argentine plants. XI. The partial structure of erysovine, erysodine, and erysopine
1. Treatment of the liberated alkaloids of Erythrina: erysovine, erysodine, and erysopine, with diazomethane gave the same methylated base, erysotrine, which was obtained in crystalline condition. 2. Oxidation of erysotrine gave m-hemipinic acid imide. When erysotrine methohydroxide was oxidized m-h...

| Sumario: | 1. Treatment of the liberated alkaloids of Erythrina: erysovine, erysodine, and erysopine, with diazomethane gave the same methylated base, erysotrine, which was obtained in crystalline condition. 2. Oxidation of erysotrine gave m-hemipinic acid imide. When erysotrine methohydroxide was oxidized m-hemipinic acid N-methylimide was obtained. 3. The constitutional relationship between the liberated alkaloids and the free alkaloids erythramine and erytbraline is confirmed. © 1951, American Chemical Society. All rights reserved. |
