Convergent synthesis of the BCDE-ring part of ciguatoxin

The BCDE-ring part of ciguatoxin has been convergently synthesized by a sequence of reactions involving coupling of the E-ring part having a Z-enal group with the B-ring part as an acyl anion equivalent, selective removal of a p-bromobenzyl protective gro
