摘要

The crystal structure of the -lactone of racemic 7-oxabicyclo[2.2.1]heptane-5-exo-iodo-6-endo-hydroxy-2-endo-carboxylic acid has confirmed the position of the lactone bridge as 2-6 and the exo-iodo substituent configuration as previously proposed from chemical and 13C NMR evidence. The iodo substituent is also involved in a short non-bonding intermolecular interaction [IO 3.289 (5) ŝ with the non-bridging lactone oxygen giving polymeric chains which link weakly hydrogen-bonded (C-HO) centrosymmetric dimer units.
