A highly convergent, enantioselective totalsynthesis of brevetoxin A is reported. The development of a [X+2+X] Horner–Wadsworth–Emmons/cyclodehydration/reductive etherification convergent couplingstrategy allowed a unified approach to the synthesis of two advanced tetracyclic fragments from four cyclic ether subunits. The Horner–Wittig coupling of the two tetracyclic fragments provided substrates
