STRUCTURE OF PERIODATE-OXIDATION PRODUCTS WITH CHARACTERISTIC PARTIAL STRUCTURES OF ZOOXANTHELLATOXIN-A, A POTENT VASOCONSTRICTIVE POLYOL FROM A SYMBIOTIC DINOFLAGELLATE
Reduction of the periodate oxidation products of zooxanthellatoxin-A with NaBH4 gave the fragment 2 (C47H76O14) and its elongated fragment 1 (C56H91O22SNa) to which the polyhydroxylated polyene structure (1), which possesses a 1,3-diepoxide and a sulfate ester functionality, was assigned on the basis of spectral data.
