  描述：

  4-(1-Methyl-2-oxo-ethyl)-piperazine-1-carboxylic acid tert-butyl ester 在 N-羟基-7-氮杂苯并三氮唑 、 三乙酰氧基硼氢化钠 、 N,N-二异丙基乙胺 、 三氟乙酸 、 N-[(dimethylamino)-3-oxo-1H-1,2,3-triazolo[4,5-b]pyridin-1-yl-methylene]-N-methylmethanaminium hexafluorophosphate 作用下， 以 二氯甲烷 、 1,2-二氯乙烷 、 N,N-二甲基甲酰胺 为溶剂， 生成 (R)-3-{(R)-1-(4-Chloro-benzyl)-2-[4-(2-diethylamino-1-methyl-ethyl)-piperazin-1-yl]-2-oxo-ethylcarbamoyl}-3,4-dihydro-1H-isoquinoline-2-carboxylic acid tert-butyl ester

  Privileged structure based ligands for melanocortin-4 receptors—Aliphatic piperazine derivatives

  摘要：

  Aliphatic carbocyclic replacement of the benzyl group of compound I yielded compounds with high affinity for the melanocortin-4 receptor (MC4R). Compounds with a cyclohexyl group showed a consistent high affinity, while different polar groups with less basicity were good replacements for the original diethyl amines. Substitution of the polar group found in these privileged structures with an aliphatic moiety produced compounds with high affinity for MC4R. (c) 2006 Elsevier Ltd. All rights reserved.
