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.
