  Total Synthesis of Halicholactone and Neohalicholactone¹

  摘要：

  The total synthesis of the marine natural products neohalicholactone (1) and halicholactone (2), in enantiomerically pure form, are reported. Key steps in the synthesis of each compound include a cis-selective Wittig reaction, stereoselective cyclopropanation, nine-membered lactone formation using the Yamaguchi method and late-stage stereoselective Cr(II)/Ni(II) mediated coupling of vinyl iodides 39 and 50 with aldehyde 14. In the case of the neohalicholactone synthesis the two major components which were coupled in this convergent synthesis were each derived from the enantiomers of commercially available malic acid. The synthesis served to confirm the original assignment of absolute configuration which was made by Yamada and Clardy. We also demonstrated, through the preparation of diastereoisomers, that another reported compound closely related to neohalicholactone is likely to be the C-15 epimer 67.

  Efficient shortcut: The use of the well‐known cyclopropanation reaction provided facile access to the main fragment of halicholactone with excellent enantioselectivity and diastereoselectivity in only five steps (see scheme). This enabled the total synthesis of halicholactone with an overall yield of 11.2 % in the shortest synthetic route so far.

  日期：1998.2.1

  An efficient synthesis of a known precursor of halicholactone (1a) and neohalicholactone (1b) has been developed using the strategically functionalized key cyclopropane intermediate 2, which in turn has been synthesized via stereoselective cyclopropanation of trans-cinnamyl alcohol in the presence of the chiral dioxaborolane ligand 4. Elaboration of the above bifunctional cyclopropane to the target molecule was achieved in a relatively short reaction sequence and in good overall yield, representing a formal synthesis of the title compounds.
