概要
- 論文の詳細を見る
It has been found that the crude acetone adducts of quaternary protoberberinium salts, dehydrocorydalinium chloride (I), 13-methylberberinium chloride (VI) and berberi-nium chloride (VII), were contaminated with about a few per cent of 8,13a-propanoberbine derivatives, III, X and XI, respectively, as a result of intramolecular Michael condensation of each acetone adduct. The presence of these compounds was deduced from the direct isolation or from the product analysis of the reaction using a crude acetone adduct as a starting material.
