Description:
( + ) - N -formylnorglaucine ( 1 ), an aporphine alkaloid containing a formyl group linked to the heterocyclic nitrogen, was isolated from leaves of Unonopsis stipitata , an Amazon medicinal plant. The chemical structure was characterized based on 1D and 2D NMR spectroscopy and HRESIMS. NMR spectra revealed that 1 is composed of two rotamers ( 1a and 1b ) in a ratio of approximately 2:1. In addition, the fragmentation behavior of 1 displayed an unusual fragmentation pattern compared to regular aporphine alkaloid. Thus, this compound is reported for the first time as a natural product in this study. This article is protected by copyright. All rights reserved.
