✦ Synopsis
A five-step chemoenzymatic synthesis of (-)-(1R, SS)-cyclosarkomycin 2 has been achieved starting from commercial racemic bicycloheptenone 3. The strategy developed involved -as key stepsan enantioselective microbiologically catalyzed Baeyer-Villiger oxidation followed by a chemical regioselective epoxide ring opening.
