摘要：

The titled compound 5a reacts with trialkyl phosphites and dialkyl phosphonates to give, in each case, two conformers (A + B) of the corresponding phosphonate 8 and 9. The yields of the two isomers were estimated on the basis of P-31 NMR data. Besides, structures 8 and 9 were supported by analytical and spectroscopic measurements of the major isomer 8A and 9A. The rotational isomers were assigned in terms of the Newman projection and NMR data. Relative ratios were studied in the light of dynamic NMR spectroscopy.
