the resultant α,ω-dialkenoic ester. An expeditious synthesis of the (5S,6R,11S,14R)-isomer of acremodiol was developed via a convergent route. One of the required buildingblocks was synthesized earlier via two sequential lipase-catalyzed secondary carbinol acetylations. The other unit was derivedfrom (R)-2,3-cyclohexylideneglyceraldehyde as a chiral template. The bismacrolide skeleton was constructed

A first totalsynthesis of (3R,4S)-4-hydroxylasiodiplodin is described starting from methyl acetoacetate and a commonly available carbohydrate, d -mannitol, which is regularly used in organic synthesis. The facile and stereoselectiveapproach involves the Barbier allylation and a ring-closing metathesis as key steps.
