Resumen:
In this work we present efficient formal syntheses of several biologically interesting natural products (showdomycin, goniofufurone, trans-kumausyne) and their novel carba analogues by applying different Baeyer-Villiger monooxygenases. This strategy provides access to tetrahydrofuran-based natural products, C-nucleosides and both antipodes of the corresponding carba analogues in high optical purities (up to >95% ee) starting from simple achiral and commercially available building blocks (tetrabromoacetone, furan and cyclopentadiene). The striking key features of this chemo-enzymatic approach are the introduction of four stereogenic centers in as few as three reaction steps within a desymmetrization approach and the short-cut of several reaction sequences by the implementation of a biocatalytic step.
