Bioactive natural compounds

Two new aporphine alkaloids, N-nitrosoanonaine (1) and N-nitrosoxylopine (2), were isolated from the aerial parts of Duguetia furfuracea, a weed found in several Brazilian regions. Their structures were elucidated by NMR analysis, CHN analysis, CD, IR, and MS data. The single-crystal X-ray strucutural determination of the structure of 1 was also perfomed.
