✦ Synopsis

The assignments of the proton and carbon signals and conformations of substituted 2-aryl-trans-decahydroquinolin-4-ones were determined using a combination of 'H, "C, COSY and HETCOR spectral data. Analysis of the spectral data reveals that these compounds exist predominantly in twin-chair conformations with the aryl and alkyl substituents in the equatorial orientation. Introduction of an alkyl group at C-3 causes a flattening of the ring about the C-2-C-3 bond. From the proton-proton coupling constants (J9,10) the junction between the rings is found to be trans.

1H and 13C NMR resonance assignments and conformational assignments were carried out for four N-nitroso-2phenyl-trans-decahydroquinolin-4-ones. In addition to conventional 1D NMR methods, 2D shift-correlated NMR techniques (1H-1H COSY, 1H-1H NOESY and 1H-13C HETCOR) were used for the signal assignme

Substituents placed on the phenyl rings of 2,3-diphenyl-1,3-thiazolidin-4-one affect the electron density surrounding both the methine proton and the C(2) carbon. These changes are reflected in the differing chemical shifts for these atoms relative to the parent compound. The other carbons in the he
