Computational NMR Structural Revision of Marinoaziridines A and B

The putative structures of alkaloids marinoaziridine A and B, the last a recent target of total synthesis, are here revised, on the basis of NMR computer-assisted structural elucidation and DFT prediction of H and C chemical shifts, as pyrroloquinoline alkaloids structurally very similar to the marinoquinolines isolated from the same source.
