The first total synthesis or (-)-aplyolide A(+). (16S)-methyloxacyclohexadeca-(5Z, 8Z, 11Z, 14Z)-tetraen-2-one, 1 is reported. The synthesis is based on three consecutive couplings of terminal alkynes with propargylic halides and proves the absolute configuration of the stereogenic center of the natural product.
