A concise and modular synthesis of pyranicin.
A modular, 13-step synthesis of the tetrahydropyran-containing annonaceous acetogenin pyranicin is reported. Key features are the use of an Achmatowicz oxidation-Kishi reduction sequence for the assembly of a pyranone from a furan and the application of Fu's alkyl-alkyl Suzuki coupling for subunit union.
