A Catalytic Model for the Dioldehydratase Reaction

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.
BAEYER-VILLIGER OXIDATION WITH Me3SiOOSiMe3 UNDER ASSISTANCE OF SnCl4 OR BF3-OEt2.

Treatment of ketones with bis(trimethylsilyl) peroxide and Lewis acid such as SnCl//4 or BF//3-OEt//2 in dichloromethane at room temperature affords esters in fair to excellent yields. Jasmine lactone is synthesized from 2- left bracket (Z)-pentenyl right bracket cyclopentanine by means of Me//3SiOOSiMe//3-BF//3-OEt//2 system without any protection of the carbon-carbon double bond. The oxidation of enol acetates of ketones to alpha -hydroxy (or alpha -acetoxy) ketones with Me//3SiOOSiMe//3-FeCl//3 system is also disclosed.
