Preparation of novel analgesics via diastereoselective nucleophilic addition to 1-dimethylamino-2-methylpentan-3-one
摘要:
The diastereoselective synthesis of naphthyl amino alcohols via nucleophilic addition to raceMic 1-dimethylamino-2-methylpentan-3-one was studied. The use of the appropriate experimental conditions allowed the synthesis of both diastereoisomers. The relative configurations were established via NOESY experiments. (C) 2003 Elsevier Ltd.

The polymerizable composition and the liquid crystal composition containing the polymerizable compound of the present invention have favorable storage stability as evaluated on the basis of the occurrence of precipitation, separation, or the like of crystals during storage. The present invention relates to a polymerizable compound, a liquid crystal composition which contains the compound, and further a liquid crystal display element which contains an optically anisotropic material which is a cured product of the liquid crystal composition, or a cured product which controls alignment of liquid crystal molecules. That is, the present invention relates to a polymerizable compound, and a liquid crystal composition containing the polymerizable compound which contains the polymerizable compound and a liquid crystal compound. The polymerizable compound is a compound represented by General Formula (I), and is useful for an optically anisotropic material, a retardation layer, an alignment film, or a polarizing layer.
A new series of arylalkyl- and alkenylamines was designed, synthesized, and evaluated for binding to sigma(1) and sigma(2) receptors. Many compounds exhibited nanomolar affinity for sigma(1) subtype receptor with good selectivity over sigma(2). A molecular modeling study was conducted in order to rationalize the experimental data, and the structure-receptor affinities are discussed. (c) 2006 Elsevier Ltd. All rights reserved.
Diastereoselective synthesis of chiral nonracemic naphthylaminoalcohols with analgesic activity
The diastereoselective synthesis of chiral nonracemic naphthylaininoalcohols has been accomplished. The diastereoisomers, obtained in high enantiomeric excesses, were investigated by H-1 NMR and HPLC analyses. The configurational assignment was performed by NOESY H-1 NMR spectroscopy. Pharmacological evaluation of the analgesic activity by means of the hot plate test is described. (C) 2004 Elsevier Ltd. All rights reserved.
