- 論文の詳細を見る
Solvent effects on the dimerization of 16,17-dehydrodigitoxigenin 3-acetate (I) were investigated. Heating of I in less polar solvents, such as toluene, xylene, dioxane or tetrahydrofuran, gave the dimer III as the main product, in similar yields. The reaction in slightly basic media, such as toluene containing sodium acetate or dimethylformamide, afforded an isomeric dimer IV preferentially. The structure of IV was established on the basis of its spectral data and anhydration reaction in contrast to those of III. A mechanism is proposed for the formation of IV from I.
