Enantioselective total synthesis of brevetoxin A: convergent coupling strategy and completion

Crimmins, Michael T.,Zuccarello, J. Lucas,McDougall, Patrick J.,Ellis, J. Michael

supporting information; experimental part, p. 9235 - 9244 (2010/04/05)

A highly convergent, enantioselective total synthesis of brevetoxin A is reported. The development of a [X+ 2+ X] Horner-Wadsworth-Emmons/ cyclodehydration/reductive etherification convergent coupling strategy allowed a unified approach to the synthesis o
