Lipase B from Candida antarctica catalyzes the oxidative ring expansion of furfuryl alcohols in the presence of aqueous hydrogen peroxide to yield functionalized pyranones under mild conditions. The corresponding piperidinone derivatives can be obtained by a similar enzymatic rearrangement of N-protected furfurylamines.
