In the title compound, C(27)H(21)NO, the piperidine ring adopts a chair conformation. The mean plane through the piperidine ring makes dihedral angles of 49.27 (5) and 63.07 (5)° with the naphthalene ring systems. In the crystal, mol-ecules are linked into dimers via pairs of inter-molecular C-H⋯O inter-actions, generating ten-membered R(2) (2)(10) ring motifs. C-H⋯π inter-actions further stabi...

In the title compound, C(22)H(23)Cl(2)NO(4), the piperidine ring adopts a distorted boat conformation. The meth-oxy groups lie in the plane of the benzene rings to which they are attached. The benzene rings are oriented at angles of 84.3 (1) and 76.8 (1)° with respect to the best plane through the piperidine ring. The crystal packing is stabilized by intermolecular C-H⋯O inter-actions.

In the title mol-ecule, C(21)H(25)NO, the piperidine ring adopts a chair conformation. The benzene rings and one of the methyl groups attached to the piperidine ring have equatorial orientations. The dihedral angle between the two benzene rings is 72.53 (9)°. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds. Weak C-H⋯π inter-actions involving the benzene rings are also present in t...

We designed and synthesized 4,4'-(piperidin-4-ylidenemethylene)bisphenol derivatives as novel tunable estrogen receptor (ER) modulators. The introduction of hydrophobic substituents on the nitrogen atom of the piperidine ring enhanced ERα binding affinity. In addition, the introduction of four methyl groups adjacent to the piperidine ring nitrogen atom remarkably enhanced ERα binding affinity. ...

In the title compound, C(23)H(26)ClNO(4), the piperidine ring adopts a distorted boat conformation. The two methoxy-phenyl groups at the 2 and 6 positions of the piperidine ring are in axial and equatorial orientations. An intra-molecular C-H⋯Cl inter-action is observed. In the crystal, the mol-ecules are linked into zigzag chains along the b axis by C-H⋯π inter-molecular inter-actions.

Ix the course of a research undertaken for another purpose I had occasion to compare the actions of several compounds of piperidine, and, as my results differ somewhat from those of other workers in this field, I have thought it wcll to publish them now, as I see no prospect oi prosecuting the subject further. The substances examined were piperidine~ a-methylpiperidine, a-ethylpiperidine~ and c...

In order to discover novel eco-friendly lead compounds for plant pathogenic fungi control, a series of benzaldehyde thiosemicarbazide derivatives with a piperidine moiety have been designed and synthesized. Fungicidal activities of all the synthesized compounds were evaluated in vitro. The results indicated that all the title compounds exhibited moderate to good fungicidal activities. Compound ...

When meperidine (Demerol) was shown to possess marked analgesic properties (Eisleb and Schaumann, 1939) and thus became the first potent synthetic analgesic drug, the importance of the 1,4-substituted piperidine nucleus in providing analgesic activity became apparent. Many modifications of this basic chemical structure have been synthesized and studied pharmacologically in an attempt to achieve...

A series of piperidine-based derivatives were identified as novel and potent inhibitors of the influenza virus through structural modification of a compound that was selected from a high-throughput screen. Various analogues were synthesized and confirmed as inhibitors. The structure–activity relationship (SAR) studies suggested that the ether linkage between the quinoline and piperidine is crit...

A new series of novel heterocyclic compounds containing both tetrazoles and piperidine nuclei together, namely, 1-(1-aryl-1H-tetrazol-5-yl)-2-(piperidin-1-yl)ethanone (22-28), were synthesized by the treatment of the respective 2-chloro-1-(1-aryl-1H-tetrazol-5-yl)ethanone (15-21) with piperidine in acetonitrile for 6 h. A series of novel tetrazole substituted piperidine derivatives were synthes...
