Fragmentation of tertiary cyclopropanol compounds catalyzed by vanadyl acetylacetonate
摘要:
Tertiary cyclopropanol compounds react with a catalytic amount of vanadyl acetylacetonate in the presence of oxygen affording beta-hydroxyketones and beta-diketones. For 3-substituted-bicyclo[4. 1.0]alkanols, peroxides are obtained, as are the beta-hydroxyketones. Conversely, 2-ethoxycarbonylcyclopropyl silyl ethers produce ethyl gamma-oxocarboxylate derivatives given the same reaction conditions. (c) 2005 Elsevier Ltd. All rights reserved.
