| 摘要 |
The present invention relates to a process for preparing racemic narwedine (which can be can be kinetically resolved) to yield (-)-narwedine and which is the biogenic precursor of (-)-galanthamine) and the use thereof as a starting material for producing (-)-galanthamine. The invention further includes processes for preparing (-)-galanthamine and (-)-galanthamine hydrobromide, as well as related novel compounds.
