The C 15 -C 28 fragment of the paclitaxel-like antimicrotubule agent laulimalide has been synthesized in 12 linear steps from known epoxide 5, with an overall yield of 16%. The methyldihydropyran ring of the side chain was efficiently prepared using ring-closing olefin metathesis chemistry. The 19,2
A stereocontrolled synthesis of the C15±C27 fragment of laulimalide is described. Key features are a divergent±convergent synthesis from (R)-glycidol, an interesting formation of a trisubstituted double bond via ring closing metathesis with Grubbs' ruthenium catalyst and a site selective protection
