  Process Development of CP-481715, a Novel CCR1 Antagonist

  摘要：

  Process development for the synthesis of 2-quinoxalinecarboxamide, N-[(1S,2S,4R)-4-(aminocarbonyl)-1-[(3-fluorophenyl)methyl]-2,7-dihydroxy-7-methyloctyl] is described. An optimized,and streamlined process starting from lactone 2 was developed: Lactone 2 was alkylated diastereoselectively with prenyl bromide, followed by deprotection of the N-Boc group and concomitant hydration of the olefin. Aminolysis of the lactone in methanolic ammonia afforded the titled compound.

  an effective, environmentally benign reagent for the deprotection of tert-butyl carbamates, tert-butyl esters, and tert-butyl ethers. The reaction conditions are mild and offer good selectivity in the presence of other acid-sensitive groups, including CBZ carbamates, azetidine, benzyl and methyl esters, TBDMS, and methyl phenyl ethers. The mildness of the reaction is further demonstrated in the synthesis

  磷酸水溶液（85重量％）是用于脱保护的有效，环境友好的试剂叔丁基氨基甲酸酯，叔丁基酯，和叔-丁基醚。反应条件温和，在其他酸敏感基团（包括氨基甲酸CBZ，氮杂环丁烷，苄基和甲基酯，TBDMS和甲基苯基醚）存在下，具有良好的选择性。反应的温和性在克拉霉素衍生物4的合成中得到了进一步证明，其中叔酸在环状氨基甲酸酯，内酯，缩酮，乙酸酯和可差向异构的甲基酮官能团存在下，除去丁酯。该反应保留了底物的立体化学完整性。反应产率高，后处理方便。

• Case Study of a γ-Butyrolactone Alkylation with 1,3-Dimethyl-2-imidazolidinone as a Promoter
  作者：Bryan Li、Richard A. Buzon、Michael J. Castaldi

  DOI：10.1021/op010224h

  日期：2001.11.1

  1,3-Dimethyl 2-imidazolidinone (DMI) is of lower toxicological risk than 1,3-dimethyl-3,4,5,6-tetrahydro-2(1H)-pyrimidinone (DMPU), hexamethyl-phosphorus triamide (HMPT), and hexamethylphosphoramide (HMPA). Formation of dialkylation byproducts is a common problem in lactone alkylation. DMI, used in stoichiometric amount, increases the rate of alkylation of gamma -butyrolactone 1 by >30-fold, therefore minimizing the dialkylation in multi-kilogram preparations. The isolated yield of the monoalkylated product 2 is >90%. The reaction protocol is also demonstrated to work on other lactone substrates and alkylating agents.
