A formaltotalsynthesis of the marine macrolide iriomoteolide 3a is described. Salient features of the synthesis include the elaboration of a β‐keto phosphonate derived from D‐(−)‐tartaric acid and the extension of a chiral butyrolactone derived fromL‐glutamic acid. Ring‐closing metathesis is employed to construct the macrolactone core of the natural product.

A number of chiral methyl-branched building blocks have been synthesized starting from (4S)-4-methyltetrahydro-2H-pyran-2-one, and the possibility for using them for the preparation of mealworm beetle, rhinoceros beetle, and earth-boring dung beetle pheromones and many other biologically active compounds has been demonstrated.
