A synthesis of the C1–C15 domain of the halichondrins [PDF]

open access: yesTetrahedron Letters, 2008
A concise route to the C1-C15 domain of the halichondrins is described. The key reaction is the conversion of a furfuryl alcohol to a pyranone. The stereocenter of this pyranone serves as the starting point for the other 8 stereocenters.
