Conformational analysis. 33. Carbon-13 nuclear magnetic resonance spectra of saturated heterocycles. 5. cis-Decahydroquinolines. Vierhapper, Friedrich W.; Eliel, Ernest L. (William Rand Kenan, Jr.-Lab., Univ. North Carolina, Chapel Hill, N. C., USA). J. Org. Chem., 42(1), 51-62 (English) 1977. CODEN: JOCEAH. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) The 13C NMR spectra of cis-decahydroquinoline, its two epimeric 3-, 6-, and 8-methyl as well as its 10-methyl, 3.alpha.,10-, 3.beta.,10- and 8.alpha.,10-dimethyl homologs, and the corresponding N-methyl compds. were recorded. Configurational and conformational assignments were made on the basis of 13C and 1H NMR spectra. The parent, 10-methyl, 6.beta. 583-60-8 and 60490-18-8 are also in the experiment.-methyl, and 8.beta.-methyl compds. are conformationally heterogeneous, according to low-temp. 13C NMR spectroscopy. Signals in the 13C spectra were assigned on the basis of those of the parent compds. with the help of parameters previously established in the trans-decahydroquinoline series. The previously reported upfield shift due, formally, to an antiperiplanar lone pair on nitrogen bearing alkyl [anti-:N(Me)-C-C] and the downfield shift caused by steric compression of syn-axial methyl groups were confirmed. Groups to which syn-axial substituents are attached are also shifted downfield. Shift parameters of the type introduced by Grant and co-workers are tabulated for the cis-decahydroquinoline series. The 13C spectra of .DELTA.1,9-octahydroquinoline and several of its methyl homologs were recorded. Conformational equilibria in variously substituted cis-decahydroquinolines are discussed. .

HClO4 by cyclohexanone (I) and 2-, 3-, and 4-methylcyclohexanone and the concn. dependence of the reaction rate were examd. The Ce(IV) concn. was detd. by amperometric titrn. with NaO2CCO2Na. The proposed radical mechanism explains the rapid redn. of 12 mmol of Ce(IV) by 1 mmol of I. .
