Total synthesis of (-)-laulimalide: Pd-catalyzed stereospecific ring construction of the substituted 3,6-dihydro[2H]pyran units

(Chemical Equation Presented) The potent anticancer agent (-)-laulimalide (1) was prepared through a versatile method that should allow access to other marine natural products. Key steps included a Pd-catalyzed 1,3 chirality transfer of an allylic alcohol

Synthetic approaches towards laulimalide: Synthesis of the C12-C29 fragment

A synthesis of the C12-C29 fragment of laulimalide 1 is described. This synthesis involves the Julia trans-olefination as a key step.
