Nuclear magnetic resonance, force field, and MNDO studies on 1-methoxycycloalkenes

The 1H, 13C, and 17O NMR spectra of 4- to 9-membered 1-methoxycycloalkenes have been recorded in CDCl3 solution. The 17O NMR chemical shifts reveal unexpectedly large and irregular variations with ring size. The other NMR shift data suggest that these variations are due to differences in the relative amounts of planar and nonplanar conformers about the O-C(sp2) bond. The same NMR data also suggest that whereas the MeO groups of the 5- to 9-membered ethers adopt mainly the expected planar s-cis conformation, the 4-membered ether exists predominantly in the exceptional s-trans conformation. The geometries of and charge densities in these ethers have been studied by force field (COSMIC, MM2) and MNDO calculations.

Synthesis, 17O NMR spectroscopy and structure of 2-trifluoroacetyl-1-methoxycycloalkenes

Among the synthesis of a series of five well-known 2-trifluoroacetyl-1- methoxycycloalkenes derived from cyclopentanone and substituted cyclohexanones, this paper describes the synthesis of three new 2-trifluoroacetyl-1- methoxycycloalkenes derived from cycloheptanone, cyclooctanone and cyclododecanone in 60-68% yield. Subsequently, the 17O NMR chemical shift analysis of the carbonyl and the methoxy groups for these cyclic molecules clearly showed the electron push-pull phenomenon and revealed large and irregular variations of 17O NMR chemical shifts with the ring size. Finally, a more stable conformation of these trifluoroacetyl-containing cycloalkenes was determined by energy minimization calculations using Austin Model 1 (AM1) semi-empirical method and correlations between 17O NMR data and torsion angles or oxygen net charge calculated by AM1 semi-empirical method were performed.
