  实用的羧酸催化还原胺化

  摘要：

  我们报道了使用羧酸作为标称亲电子试剂的胺的还原烷基化反应。该两步反应利用了苯基硅烷的双重反应性，涉及硅烷介导的酰胺化，然后是 Zn(OAc) 2催化的酰胺还原。该反应适用于多种胺和羧酸，并已得到大规模证明（305 mmol 胺）。抗逆转录病毒药物马拉韦罗的聚合合成中体现了叔酰胺中间体和仲酰胺中间体的还原速率差异。机理研究表明，酰胺化步骤中残留的 0.5 当量羧酸负责生成具有增强反应性的硅烷还原剂，从而可以还原以前在锌/苯基硅烷体系中不反应的仲酰胺。

  Efficient Transamidation of Primary Carboxamides by in Situ Activation with N,N-Dialkylformamide Dimethyl Acetals

  摘要：

  Two protocols for the transamidation of primary amides with primary and secondary amines, forming secondary and tertiary amides, respectively, are described. Both processes employ N,N-dialkylformamide dimethyl acetals for primary amide activation, producing N'-acyl-N,N-dialkylformamidines as intermediates, as widely documented in the literature. Although the latter intermediates react irreversibly with amines by amidinyl transfer, we show that in the presence of certain Lewis acid additives efficient acyl transfer occurs, providing new and useful methods for amide exchange. In one protocol for transamidation, the N'-acyl- N,N-dialkylformamidine intermediates are purified by flash-column chromatography and the purified intermediates are then treated with an amine (typically, 2.5 equiv) in the presence of scandium triflate (10 mol %) in ether to form in high yields the products of transamidation. In a second procedure, N'-acyl-N,N-dialkylformamidines are generated in situ and, without isolation, are subjected to transamidation in the presence of zirconium chloride (0.5 equiv) and an amine (typically 2 equiv). A variety of different primary amides and amines are found to undergo efficient transamidation using the methods described.

  drug-resistant rates. In an attempt to develop new antitubercular agents, 35 compounds were synthesized, most of them bearing a carbamate and enantiopure amino acid moiety. These compounds had their activity evaluated toward a Mycobacterium tuberculosis strain (ATCC 27294) and cytotoxicity against fibroblast MRC-5 cells (ATCC CCL-171). Three of the prepared derivatives presented a good antimicrobial inhibition

  Aminocarbonyloxymethyl ester prodrugs are known to undergo rearrangement in aqueous solutions to form the corresponding N‐acylamine side product via an O → N intramolecular acyl transfer from the carbamate conjugate base. Novel aminocarbonyloxymethyl esters of diclofenac and flufenamic acid containing amino acid amide carriers were synthesized and evaluated as potential prodrugs displaying less ability

  Twenty-one analogs based on the structure Tyr-D-Arg-Phe-X (X=OH, alkyl ester, alkylamide or amino acid having a different carbon chain) were synthesized by the solution method and their analgesic activities were tested after subcutaneous (s. c.) administration in mice. Most tripeptide alkylamides showed no analgesia at a dose of 10 mg/kg, s. c. However, some tripeptide alkylamides having the hydroxyl group on the alkyl moiety showed greater activity than morphine. Introduction of the carboxyl group on the alkyl moiety also led to tetrapeptide analogs with potent analgesia, e. g., the compound with X=β-alanine is 33 times more potent than morphine on a molar basis. These results suggest that proper carbon chain lengths and the presence of an oxygen atom at the fourth position are important for high analgesic activity in the series of D-Arg2-dermorphin analogs.

  通过溶液法合成了基于结构Tyr-D-Arg-Phe-X（X=OH，烷基酯，烷基酰胺或具有不同碳链的氨基酸）的21种类似物，并在小鼠皮下（s.c.）给药后测试了它们的镇痛活性。大多数三肽烷基酰胺在10 mg/kg，s.c.剂量下没有镇痛作用。然而，一些在烷基部分具有羟基的三肽烷基酰胺显示出比吗啡更大的活性。在烷基部分引入羧基也导致具有强效镇痛作用的四肽类似物，例如，X=β-丙氨酸的化合物在摩尔基础上比吗啡强33倍。这些结果表明，适当的碳链长度和在第四位存在氧原子对于D-Arg2-dermorphin类似物系列中的高镇痛活性是重要的。
