Derivatives of phenanthro[1,2-d]azepine, a previously unknown heterocyclic system, can be easily obtained from aporphine alkaloids by successive pyridine–pyridine and pyridine–azepine recyclizations. The starting glaucine was used as an illustrat

The reaction of acetoxyallobetulin with HClO4 in refluxing Ac2O led to a mixture of diacetoxyheterobetulin (3β,28-diacetoxy-18α,19βH-urs-20-ene), diacetoxymoradiol (3β,28-diacetoxy-olean-18(19)-ene), 3β-acetoxy-21β-acetyl-20β,28-epoxy-18α,19
