Correlations of Stereochemistry and Heteroatom Configurations with 17O Chemical Shifts in Substituted 1-Hetera-4-cyclohexanones
The 17O chemical shifts for the oxygen atom of the carbonyl group have been measured for several substituted 1-hetera-4-cyclohexanones and selected 3,7-diheterabicyclo<3.3.1>nonan-9-ones in D3CCN/H3CCN at 70 deg C.The heteroatoms included N, O, S, Se, and P.Sharp trends in shielding and deshielding for C=17O were observed with substituents at various positions.For example, deshielding effects are detected when phenyl or methyl groups are present at the 2,6-positions (alpha to the C=O).Increased deshielding was observed in the case of trans-2,6-diphenyl analogues as compared with the cis-2,6-diphenyl analogues.A shielding eff ect was seen when methyl groups were present at the 3,5-positions (beta to the C=O).Negligible changes in C=17O chemical shifts occurred in 1-aza and 1-oxa analogues as compared with cyclohexanone.In contrast, the sulfur, selenium, and phosphorus analogues showed a significant downfield shift for C=17O as compared to cyclohexanone.For certain 3,7-diheterabicyclo<3.3.1>nonan-9-ones, a shielding effect on the C=17O resonance was seen which was reminiscent of the effect elicited with substituents at the 3,5-positions (alpha to the C=O) in the 1-hetera-4-cyclohexanones.Interstingly, the related system tropinone, as compared to that in N-methyl-4-piperidinone, showed a deshielding for C=17O which was quite similar to that found in 2,6-substituted (beta to the C=O) 1-hetera-4-cyclohexanones compared to the corresponding parent 1-hetera-4-cyclohexanone.This suggests that the piperidinone ring in tropinone exists in a chair form in D3CCN/H3CCN at 70 deg C.
