Formal synthesis of actinoranone using a one-pot semipinacol rearrangement/Wittig reaction

Article abstract of DOI:10.1016/j.tet.2018.11.003

Here, we report a formal synthesis of the marine cytotoxic meroterpenoid actinoranone. Key steps include a semipinacol rearrangement/Wittig reaction sequence and a chiral pool approach for the syntheses of the tetralone and the ocatalin fragments, respectively. The presented route provides access to the natural product in 14 steps in the longest linear sequence.
