  摘要：

  Hydroperoxidation of C=C-bridged 2-oxabicycloalkenes in which the five- or six-membered oxacycle is fused with the five-, six-, or twelve-membered hydrocarbon ring was studied. The Cu(OAc)(2)-catalyzed decomposition of the resulting hydroperoxides afforded nine-, ten-, or fifteen-membered trans-alkenolides, respectively. The latter compounds were obtained as pairs of regioisomers, with the isomers in which the double bond is more remote from the ether oxygen atom predominating.

• Hypervalent Organoiodine-Promoted Oxidative Ring Expansions of Tributylstannyl Lactols. New and General Synthesis of Unsaturated Medium-Ring Lactones
  作者：Masahito Ochiai、Shigeru Iwaki、Tatsuzo Ukita、Yoshimitsu Nagao

  DOI：10.1246/cl.1987.133

  日期：1987.1.5

  A new ring expansion route to olefinic lactones was developed. Oxidative 1,4-fragmentation of tributylstannyl lactols utilizing (diacetoxyiodo)bezene under mild conditions gave unsaturated medium-ring lactones stereospecifically in good yields. The relative stereochemistry of tributylstannyl group of the lactols determines the double bond geometry of the lactones.

  5-(Tetrahydro-2-furyl)pentanoic trifluoroacetic anhydride reacts in the presence of trifluoroacetic acid to yield 6-trifluoroacetoxy-9-nonanolide together with (E)-non-5-en-9-olide; treatment of the same mixed anhydride with titanium(IV) chloride gives 6-chloro-9-nonanolide, and its reaction with trifluoroacetic acid in the presence of sodium iodide leads to 6-iodo-9-nonanolide.
