General description

(±)-cis-bicyclo(3.2.0)hept-2-en-6-one undergoes preparative scale Baeyer–Villiger biooxidation at high concentration using recombinant Escherichia coli biocatalyst and adsorbent resin (in situ substrate feeding and product removal)[1].

Application

(±)-(1S,5R)-cis-bicyclo(3.2.0)hept-2-en-6-one may be used:
  • to study enantioselective Baeyer–Villiger oxidation of (±)-cis-bicyclo(3.2.0)hept-2-en-6-one with H2O2 mediated by Co(Salen) catalyst in water with surfactants[2]
  • to investigate the extremophile enzymes (monooxygenase and hydrolases) in microorganisms isolated from deep-water petroleum reservoir and at high temperatures using fluorogenic assays and multibioreactions[3]
  • in the preparation of series of chalcone derivatives via reacton with arylaldehydes[4]

Articles

The Baeyer-Villiger oxidation is the oxidative cleavage of a carbon-carbon bond adjacent to a carbonyl, which converts the ketones to esters and the cyclic ketones to lactones.
