摘要:
Synthesis of the BC/DE ring model of brevisin, a polycyclic ether isolated from the red tide dinoflagellate Karenia brevis, is reported. Comparison of the NMR data of the BC/DE ring model with those corresponding to the same region of brevisin led to the confirmation of its structure around the acyclic juncture. (C) 2010 Elsevier Ltd.
