A series of chiral alpha-substituted cyclohexanones have been synthesized from chemoenzymatically produced chlorocyclo-hexadienediol. These highly functionalized ketones can be used in the total synthesis of diverse natural products, such as bengamides. A study of the reactivity of alpha-chlorooxiranes, common intermediates in the synthetic scheme, showed that under nucleophilic opening conditions an intermediate chloroketone may or may not form, depending on the nature of the nucleophiles present in the reaction medium. The stereochemical outcome of this reaction is presented. (c) 2005 Elsevier Ltd. All rights reserved.
