  Synthesis of tetrahydrofuran-based natural products and their carba analogs via stereoselective enzyme mediated Baeyer–Villiger oxidation

  摘要：

  In this work we present efficient formal syntheses of several biologically interesting natural products (showdomycin, goniofufurone, tratts-kumausyne) and their novel carba analogs by applying different Baeyer-Villiger monooxygenases. This strategy provides access to tetrahydrofuran-based natural products, C-nucleosides and both antipodes of the corresponding carba analogs 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.

  Microbial Baeyer-Villiger oxidation of different substrates with cyclopentanone monooxygenase (CPMO) from Comamonas NCIMB 9872 was up-scaled to benchtop fermenter scale. Conditions for cell growth and biocatalyst production were optimized, and a convenient, environmentally friendly and applicable methodology for the preparation of chiral building blocks for natural product and bioactive compound synthesis was developed by applying a resin based on the concept of in situ "substrate feeding-product removal" (SFPR). Three different ketones (4-methylcyclohexanone, rac-3-methylcyclohexanone, and 8-oxabicyclo[3.2.1] oct-6-en-3-one) were converted in 5-15 g/L scale in a conventional bioreactor, with a volumetric productivity of up to 1 g L-1 h(-1) in good to excellent yield and enantiomeric purity.
