Saxitoxin total synthesis
WebBesides, we have achieved the synthesis of 11-saxitoxinethanoic acid (SEA), which is an unusual STX derivative bearing carbon-carbon bond at the C11 position by applying Mukaiyama aldol condensation reaction with silyl enolether derived from the key intermediate of fully protected saxitoxinol.
