The fully substituted hydroisobenzofuran core of the massileunicellins containing eight contiguous stereocenters was prepared in 12 steps from (S)-(+)-carvone. Noteworthy elements of the synthesis include a one-step oxidative rearrangement/epoxidation, a novel stereoselective directed reduction of a keto diol, and a directed hydrogenation of a congested tetrasubstituted alkene.

An approach to the massileunicellins is described that employs a cycloaldol reaction to assemble the isobenzofuran bicyclic core. A stereoselective rearrangement-epoxidation-oxidation cascade and a chelation controlled addition to a hindered acyl furan are used to install the C3, C11, C12, and C13 oxygens. The synthesis establishes eight of the nine stereocenters present in the isobenzofuran core of the massileunicellins.
