Ring opening of 2,6-diaryl-3,5-diphenyl piperidine-4-one by acetic acid: Structural studies and Hirshfeld surface analysis of (E)-4-aryl-1,3-diphenylbut-3-en-2-ones

Six α,β-unsaturated carbonyl compounds have been obtained from 2,6-diaryl-3,5-diphenylpiperidine-4-one by the treatment with acetic acid. A plausible mechanism for the ring opening of 2,6-diaryl-3,5-diphenyl piperidin-4-ones is proposed. The resultant (E)

Chemistry of N-Nitroso Compounds. 1. Synthesis and Stereodynamics of N-Nitrosopiperidines and N-Nitrosopiperidin-4-ones

The stereochemistry of a series of N-nitroso-r-2,c-6-diphenylpiperidin-4-ones (10-15) and N-nitroso-r-2,c-6-diphenylpiperidines (16-18) in solution has been investigated by 1H NMR, 13C NMR, and dynamic 1H NMR spectroscopic studies.Unlike the r-2,c-6-dialkyl-N-nitrosopiperidines, which have diaxial alkyl groups, these N-nitroso-r-2,c-6-diphenylpiperidines (16-18) and N-nitroso-r-2,c-6-diphenylpiperidin-4-ones (10-15) have diequatorial phenyl groups even though the nitroso group is coplanar to the dynamically averaged plane of the piperidine ring.The rotamer populations of the N-NO orientations in the nitrosamines were derived from continuous wave 1H NMR spectral data and are correlated with the steric bulk of the substituents present at the C-3 and C-5 positions.N-Nitroso-r-2,c-6-diphenylpiperidine-4-one (10) was found to have a higher rotational barrier than N-nitroso-r-2,c-6-diphenylpiperidine (16).We attribute this difference to a greater degree of coplanarity (C3-C2-N1-C6-C5) in 10 than in 16.The rotational barriers in 10 were found to decrease as the bulk of the substituents at C3 and C5 increased.The rotational barrier in N-nitroso-r-2,c-6-diphenylpiperidine (16) was found to be lower than the reported rotational barriers of N-nitroso-r-2,c-6-dimethylpiperidine and N-nitroso-2,2,6,6-tetramethylpiperidine.

Conformational Analysis of Some N-Chloro-2,6-diphenyl-piperidin-4-ones by Kinetic and Equilibrium Methods

Confromational analysis of some substituted N-chloro-2,6-diphenylpiperidin-4-ones (I-IX) has been carried out by kinetic and equilibrium methods.The buttressing effect of alkyl substituents on vicinal phenyl groups has been observed during the kinetic and
