A simple approach for the synthesis of the C14-C28 fragment of eribulin has been developed by employing a one-pot gold-catalyzed alkynol cyclization/Kishi reduction to construct the 1,5-cis-tetrahydropyran unit and a cross-metathesis/Sharpless asymmetric
Crotylation versus propargylation: Two routes for the synthesis of the C13-C18 fragment of the antibiotic branimycin

The C13-C18 fragment 3 of the novel antibiotic branimycin was prepared along two highly stereocontrolled routes. The first one uses a standard Roush crotylation protocol, whereas the second one proceeds via an allenyl silane propargylation with unexpected stereochemical consequences, which are discussed in detail.
A divergent approach to apoptolidin and FD-891: Asymmetric preparation of a common intermediate

Biologically active Apoptolidin and FD-891 have structural similarity in their macrocyclic cores. Asymmetric preparation of a common intermediate in the total synthesis of these two macrolides is presented. A modified Masuyama Sn-allylation was employed to control the relative stereochemistry in the synthesis of the intermediate.
