Carbocyclic galanthamine analogues: construction of the novel 6H-benzo[a]cyclohepta[hi]benzofuran ring system
摘要:
Unnatural analogues of the anti-Alzheimer drug (-)-galanthamine have been synthesised using K-3[Fe(CN)](6) at the key step to construct the novel (+/-)-6H-benzo[a]cyclohepta[hi]benzofuran ring system via oxidative tandem cyclization.
