Disclosed embodiments concern a method for making substantial quantities of desired macrocycles. Disclosed ring closing reactions make the macrocycle with desired olefin geometry in excellent yield and E/Z ratio. Particular embodiments of the current method concern intermediates that are obtained from commercially available starting materials in a small number of steps, thereby illustrating the commercial importance and applicability of the disclosed method. The macrocycle produced by the ring closing reaction can be further derivatized to provide analogs of the macrocyclic compounds.
