  Photo-irradiation of α-halo carbonyl compounds: a novel synthesis of α-hydroxy- and α,α′-dihydroxyketones

  摘要：

  The reaction of g.-halo ketones (alpha-iodocycloalkanones, alpha-bromocycloalkanones, alpha-iodo-beta-alkoxy esters, and alpha-iodoacyclic-ketones) with irradiation under a high-pressure mercury lamp gave the corresponding alpha-hydroxyketones in good yields. For alpha-bromoketones, it was found that alpha-hydroxylation does not occur. However, alpha-bromoketones were convened into a-hydroxyketones in the presence of KI. In the case of alpha,alpha(1)-diiodo ketones, alpha,alpha(1)-dihydroxyketones, which up to now have scarcely been reported, were obtained. This reaction affords a new, clean and convenient synthetic method for alpha-hydroxy- and alpha,alpha(1)-dihydroxyketones. (C) 2005 Elsevier Ltd. All rights reserved.
