Structures of Acid B and Related Compounds, Oxidation Products of Lycoramine

The structures of "acid B" and its monoethyl ester, which are stepwise oxidation products of lycoramine (2), an Amaryllidaceae alkaloid, and the structure of a nitro derivative of acid B, an oxidation product of oxolycoramine (5) with nitric acid, were established as 6, 10 and 12, respecti...

Summary:The structures of "acid B" and its monoethyl ester, which are stepwise oxidation products of lycoramine (2), an Amaryllidaceae alkaloid, and the structure of a nitro derivative of acid B, an oxidation product of oxolycoramine (5) with nitric acid, were established as 6, 10 and 12, respectively, on the basis of spectral and chemical evidence.
