A Catalytic Model for the Dioldehydratase Reaction

Mueller, Peter,Retey, Janos

, p. 1342 - 1344 (2007/10/02)

The diastereoisomeric 6,7-dihydroxycycloundecyl iodides (3a), (3b), and (3c) have been synthesised; their conversion into cycloundecanone (12) in the presence of sodium borohydride and traces of cobalt complexes provides the first catalytic model for the coenzyme B12 catalysed dioldehydratase reaction.
