Configuration yessotoxin

Yessotoxin (214) is a polyether from the scallop Patinopecten yessoensis and has been implicated in diarrhetic shellfish poisoning (DSP). The structure and partial stereochemistry of yessotoxin were deduced from spectral data [219]. The relative stereochemistry of yessotoxin and the structures of two new analogues, 45-hydroxyyessotoxin (215) and 45,46,47-trinoryessotoxin (216) were also established [220]. The absolute stereochemistry of yessotoxin (214) was determined by NMR spectroscopy using a chiral anisotropic reagent [221]. The absolute configuration at C45 in 45-hydroxyyessotoxin (215), isolated from P. yessoensis, was determined by the use of a modified Mosher s method [222]. [Pg.653]
