  Total Synthesis and Stereochemistry of Alternaric Acid

  摘要：

  Determination of the stereochemistry and the total synthesis of alternaric acid 1 has been achieved. The stereostructure of 1 has been elucidated by stereoselective synthesis of four diastereoisomers of the C(9)-C(14) fragment 6, which had been obtained as a degradation product during structural studies. Key reactions of the total synthesis of 1 include the Julia olefination of tertiary aldehyde 6 and phenylsulfone 7 and novel one-pot construction of 3-acyl-4-hydroxy-5,6-dihydro-2-pyrone via Fries-type rearrangement of the O-enol acyl group of beta-keto-delta-valerolactone toward the a-position of the delta-lactone. The absolute configuration of alternaric acid has been shown to be that illustrated in structure 1. The modified Fries-type rearrangement method has also been extended to the synthesis of some other compounds containing a tricarbonylmethane structure.

  A total synthesis of alternaric acid (1) has been achieved. Key reactions include the Julia olefination of tertiary aldehyde 4 and phenylsulfone 5, and novel one-pot construction of 3-acyl-4-hydroxy-5,6-dihydropyrone via Fries type rearrangement of O-enolacyl group of beta-keto-delta-valerolactone toward alpha-position of the delta-lactone. The absolute configuration of alternaric acid has been shown to be that illustrated in structure 1.
