The first stereoselective synthesis of polyketide natural product (3R,6S)-6-hydroxylasiodiplodin (1) has been described starting from commonly available starting materials d-mannitol and 2,4,6-trihydroxybenzoic acid. The key reactions involved are Keck asymmetric allylation, Stille coupling, De Brabander's esterification, and ring-closing metathesis (RCM) reaction. The total synthesis was achieved in 19.3% overall yield making the route significant.
Total synthesis of diastereomeric marine butenolides possessing a syn-aldol subunit at C10 and C11 and the related C11-ketone

Two diastereomeric marine butenolides, (4S,10R,11R)- and (4S,10S,11S)-4,11-dihydroxy-10-methyldodec-2-en-1,4-olide, possessing a syn-aldol subunit at C10 and C11 have been efficiently synthesized by using a three-module coupling strategy. The enantiomeric syn-aldol modules prepared by the syn-selective aldol reaction of the norephedrine-derived chiral propionates were coupled with the chiral C3-C7 module via 1,3-dithiane bisalkylation. The butenolide ring was then installed via a high-yielding ring-closing metathesis (RCM) reaction. Oxidation of the diastereomeric C11-alcohols furnished the corresponding C11-ketones, which are produced by the same marine microorganism.

The formal synthesis of isofebrifugine, a bioactive alkaloid, was achieved via a stereoselective intramolecular Michael addition reaction from d-mannitol.
