A short and convergent strategy for the first asymmetric total synthesis of cytotoxic macrolides pestalotioprolides E and F has been developed. The key features of this synthesis include Takai olefination, Sonogashira coupling, Ni-assisted partial hydrogenation of alkyne, modified Steglich reaction to generate the ester moiety, and intramolecular Horner–Wadsworth–Emmons (HWE) olefination to complete

A practical method for the synthesis of several useful polyhydroxylatedchiralbuildingblocks has been developed. The key reaction is the kinetic resolution of (E)-1-trimethylsilyl-4-alkoxy-1-buten-3-ol or (E)-1-trimethylsilyl-5-alkoxy-1-penten-3-ol using the Sharpless asymmetric epoxidation reaction.
