Totalsynthesis of mucocin (1) was accomplished through a palladium-catalyzed cross coupling reaction of the C10C34 fragment of 1 and a newly designed γ-hydroxy butenolide subunit, which was synthesized by taking advantage of radical cyclization of an acyclic olefin having a selenocarbonate group derived from L-rhamnose.

The left-half segment of mucocin (1) was stereoselectively synthesized through a coupling reaction of a tetrahydropyranyl aldehyde and a tetrahydrofuran derivative having an ethynyl group, which were prepared from 2,3,4,6-tetra-O-benzyl-D-galactono-1,5-lactone and 2,5-anhydro-D-mannitol, respectively.
