    Synthesis of the enantiomeric forms of α- and γ-damascone starting from commercial racemic α-ionone
    摘要:
    A straightforward synthesis of both enantiomers of alpha- and gamma-damascone is described. The title compounds were prepared by a divergent pathway starting from the enantiomeric forms of (6RS,7SR,9RS)-7-hydroxy-7,8-dihydro-alpha-ionol and of (6RS,7SR,9RS)-7hydroxy-7.8-dihydro-gamma-ionol. These building blocks were obtained from racemic alpha-ionone in four and five steps, respectively. The 7-hydroxy group was introduced by regio- and diastereoselective epoxidation of the conjugated double bond followed by reductive opening of the oxirane ring. The hydroxy-ketone obtained was reduced diastereo selectively to trans-alpha-diol that could be converted to the trans-gamma-diol by photochemical isomerization. Both diols were then resolved by lipase-mediated acetylation. (c) 2006 Elsevier Ltd. All rights reserved.

    (+)-Epoxy-α-dihydroionone (2) is formed completely stereospecifically from (+)-α-ionone (1). Under the conditions of the Wharton reaction this epoxide gives the expected isomeric allyl alcohols 4 and 5 and, surprisingly, the bicyclic allyl alcohol 3. The structure and absolute configuration of the reaction products have been established. A common intermediate for the formation of compounds 3, 4 and

  • Diastereoface-Selective Epoxidations: Dependency on the Reagent Electrophilicity

    Substrate-imposed steric constraints can be overriden by the pronounced preference of strong peracids for epoxidation on the π face, which has the highest electron density. For example, the syn:anti ratio for reaction (1) with CF3 CO3 H in CH2 Cl2 is 82:18, that with CH3 CO3 H in toluene is 3:97.
