The title compound, C(17)H(27)NO, features a bufferfly-shaped substituted 2-propanol having an aromatic ring on the 1-carbon and a piperidine ring on the 3-carbon. The piperidine ring adopts a chair conformation and its N atom shows a trigonal coordination. In the crystal, the hy-droxy group inter-acts with the N atom of an inversion-related mol-ecule, generating an O-H⋯N hydrogen-bonded dimer.

In the title compound, 0.75C12H14ClNO2·0.25C12H14ClNO, which is an adduct comprising 0.75 4-hy-droxy-piperidin-1-yl or 0.25 4-piperidin-1-yl substituents on a common (4-chloro-phen-yl)methanone component; the dihedral angles between the benzene ring and the two piperidine rings are 51.6 (3) and 89.5 (7)°, respectively. The hy-droxy-piperidine ring is in a bis-ectional oriention (bi) with the ph...

In the mol-ecule of the title compound, C(17)H(24)N(2)O(6), the dihedral angle between the four coplanar atoms of the piperidine ring and the benzene ring is 39.2 (1)°.

Metabolic disposition of 5,5-dimethyl-2-(1-methylethylidene)-cyclohexanone (I) was examined in rats. Compound (I) was administered orally (250 mg/kg of body weight/day) to rats for 5 days. The following urinary metabolites were isolated and identified: 4,5,6,7-tetrahydro3,6,6-trimethylbenzofuran (III), 3,3-dimethylcyclohexanone (VI), 5,5-dimethyl-3-hydroxy-2-(1-methylethylidene)-cyclohexanone (...

reaction between aromatic aldehydes and 3–methyl-1-phenyl-2-pyrazoline-5-one catalyzed by nano-sio2/hclo4 in water under reflux provided a simple and efficient route for the synthesis of 4-((5-hydroxy-3-methyl-1-phenyl-1h-pyrazol-4-yl)(aryl)methyl)-3-methyl-1-phenyl-1h-pyrazol-5-ol derivatives in high yields.

We describe in this study the asymmetric synthesis of radioisotope (RI)-labeled selective glucocorticoid receptor modulator. This synthesis is based on optimization of the cinchona alkaloid catalyzed addition of 6-bromoindole to ethyl trifluoropyruvate and Negishi coupling of zinc cyanide to the 6-bromoindole moiety. [¹⁴C] Labeled (-)-{4-[(1-{2-[6-cyano-1-(cyclohexylmethyl)-1H-indol-3-yl]-3,3,3...

The carbonyl reductase from Candida parapsilosis (CPCR2) is a versatile biocatalyst for the production of optically pure alcohols from ketones. Prochiral ketones like 2-methyl cyclohexanone are, however, only poorly accepted, despite CPCR2's large substrate spectrum. The substrate spectrum of CPCR2 was investigated by selecting five amino positions (55, 92, 118, 119 and 262) and exploring them ...

The impairment of learning and memory is one of the most powerful and least understood effects of marijuana although the hippocampal formation appears to be one CNS region mediating these effects. We have shown that systemic injection of Delta9-tetrahydrocannabinol (THC), an active component of marijuana, impairs spatial learning more efficaciously in adolescent rats, compared with adult rats, ...
