摘要：

The complete H-1 and C-13 NMR assignments are reported for the novel natural product Bacillosporin D together with the known compound Bacillosporin C. These compounds containing seven rings were isolated from the mangrove endophytic fungus SBE-14 from the South China Sea. D-1 and D-2 NMR experiments, including COSY, HMQC and HMBC were used to the determination of the structures and NMR assignments. It is proposed that I was biogenetically produced by transforming 2. Transforming a lactone to an anhydride is unusual in nature. Copyright (c) 2007 John Wiley & Sons, Ltd.
