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 zooxanthelletoxin-A with NeBH 4 gave the fragment 2 (C 47 H 76 O 14 ) and its elongeted fragment 1 (C 56 H 91 O 22 SNa) to which the polyhydroxylated polyene structure (1), which possesses a 1,3-diepoxide and a sulfte ester functionality, was assigned on the basis of spectral data
