title: Synthesis of the originally proposed structures of elatenyne and an enyne from Laurencia majuscula.
abstract: A bidirectional synthesis of the originally proposed structures for the natural products elatenyne and a chloroenyne from Laurencia majuscula is described along with a reassessment of the structures of the halogenated enynes based upon a 13C NMR chemical shift/structure correlation.
