Convergent syntheses of the enantiomeric CD- and JK-ring parts of ciguatoxin, based on a coupling reaction between dithioacetal mono-S-oxide and aldehyde derivatives and reductive cyclization of the respective hydroxy ketones, have been achieved.

ciguatoxin - acyl anion equivalent - dithioacetal mono-S-oxide - convergent synthesis - reductive etherification
