The synthesis of the ABCDEF-ring of ciguatoxin 3C was achieved via a route that included anion coupling of a dimethyldithioacetal mono-S-oxide derivative corresponding to the AB-ring and an aldehyde corresponding to the EF-ring, followed by cyclizati

The EF-ring of ciguatoxin 3C, a marine toxin from the dinoflagellate Gambierdiscus toxicus, was stereoselectively synthesized by iterative use of a cyclic ether formation process based on chirality-transferring Ireland-Claisen rearrangement and ring-

Convergent synthesis of the IJKLM-ring part ( 2 ) of ciguatoxin CTX3C has been achieved from the I-ring and the L-ring parts ( 4 and 5 ) in total eight steps in 27% overall yield. The carbanion derived from 4 , stabilized by a dimethyldithioacetal S-

The C42–C52 part of ciguatoxin CTX3C ( 1 ) was synthesized from tri-O-acetyl d -glucal. The synthetic segment had a tetrahydropyran ring corresponding to the ‘C49-reduced’ L-ring of 1 , designed to avoid side reactions due to acid-labile C49 ac
