摘要：

Six omega-(1-pyrrolidine)alkanocarboxylic acid hydrohalides [C4H8N+H(CH2)(n)COOH . X-] and 1-(omega-carboxyalkyl)-1-methylpyrrolidinium hydrohalides [C4H8N+CH3(CH2)(n)COOH . X- (n = 1,2,3,4,5,10)] and their sodium and inner salts were synthesized, respectively. IR, H-1 and C-13 NMR spectra were analyzed with regard to the increasing distance effect on the interaction between the positive nitrogen atom with the negative carboxylic group. The configuration of the pyrrolidine ring was also discussed. (C) 1997 Elsevier Science B.V.
