The firststereoselectivetotalsynthesis of (–)-synrotolide has been realized by two different approaches, both starting from (S)-ethyl lactate. Both strategies used stereo- and regioselective epoxide opening with a nucleophile, aldehyde alkyne coupling and ring-closing metathesis as key steps. Judicious choice of reagents (CeCl3·7H2O and H2SiF6) for the chemoselective removal of protecting groups
