  Synthesis of 2-piperidinecarboxylic acid derivatives as potential anticonvulsants

  摘要：

  A variety of 2-piperidinecarboxamides were synthesized and evaluated for anticonvulsant activity using the MES and sc PTZ tests in mice and rats. Neurotoxicity was determined by the rotorod test. Several N-(benzyl)-2-piperidinecarboxamides exhibited potent MES activity in mice [2-CF3 14, ED50 = 29 mg/kg; 3-F 16, ED50 = 31 mg/kg; and 3-CF3 17, ED50 = 24 mg/kg]. The most active compounds in the MES test in mice were the 2,6-dimethylanilides [(R,S)-34, ED50 = 5.8 mg/kg; (R)-35, ED50 = 5.7 mg/kg; and (S)-36, ED50 = 14.8 mg/kg]. The enantiomer (S)-36 was about two-fold less potent in the MES test than (R)-35 and also was less neurotoxic. Acylation of the piperidine ring nitrogen of 12 and 34 led to a decrease in the MES activity. In the N-(alpha-methylbenzyl)-2-piperidine-carboxamides, the stereochemistry at either the 2-position of the piperidine ring or at the alpha-position of the N-(alpha-methylbenzyl) group does not significantly affect MES activity.

  日期：2008.3.27

  An enantioselective Biginelli reaction that proceeds by a dual-activation route has been developed by using a combined catalyst of a readily available trans-4-hydroxyproline-derived secondary amine and a Bronsted acid. Aromatic, heteroaromatic, and fused-ring aldehydes were found to be suitable substrates for this multicomponent reaction. The corresponding dihydropyrimidines were obtained in moderate-to-good

  A series of N-formamides derived from pipecolinic acid have been synthesized and tested as Lewis base catalysts for the enantioselective reduction of N-aryl imines by trichlorosilane. Through the investigation of the structure–efficacy relationship between the side amide group and catalytic performance, several highly effective catalysts were discovered. In particular, arylamido-type catalyst 5i and
