  Efficient syntheses of C20-carotene and crocetin (descrocetin) esters promoted by an acidic ionic liquid

  摘要：

  Efficient syntheses of C-20-carotene and crocetin or descrocetin esters from fumaraldehyde bis-dimethylacetal are described. The key steps of these syntheses are the reactions of fumaraldehyde and (2E,4E,6E)-octa-2,4,6-trienedial bis-dimethylacetals with alkyl vinyl or alkyl propenyl ethers promoted by the acidic ionic liquid, [emim][HSO4].(C) 2012 Elsevier Ltd.
