A diastereomer of wortmannilactone C was synthesized according to a versatile strategy from tert-butyl 3-hydroxypropanoate and ethyl (R)-3-hydroxybutanoate, by using versatile organometallic reagents to control four stereogenic centers out of five. The successful strategy consists of the construction of the C13-C17 triene by using a Liebeskind coupling and the construction of the C2-C7 triene by utilizing a Horner-Wadsworth-Emmons reaction to form the macrocycle.
