  The Chemistry of Phosphapeptides: Formation of Functionalized Phosphonochloridates under Mild Conditions and Their Reaction with Alcohols and Amines

  摘要：

  A variety of methods have been explored for the convergent synthesis of phosphonamidates and phosphonates via phosphonochloridates. In the absence of complex functionality, phosphorus pentachloride is an effective reagent for the conversion of diethyl and diisopropyl phosphonates to phosphonochloridates. Subsequent reaction with amines and alcohols provides good yields of the phosphonamidates and mixed phosphonates, respectively. However, in the presence of more complex functionality, a milder method utilizing oxalyl chloride to generate the phosphonochloridate from a monomethyl phosphonic acid is required. Aminolysis of the dimethyl phosphonates generates the requisite monomethyl phosphonic acids which are cleanly converted to phosphonochloridates and reacted with amines and primary alcohols.

  磷酸神经酰胺肽类似物作为大鼠肾或人脑金属内肽酶（脑啡肽酶，EC 3.4.24.11）和血管紧张素转化酶（ACE，3.4.14.1）抑制剂的有效性已与一系列脑啡肽类似物一起探索，其中可裂解的Gly3- Phe4酰胺键已被膦酰胺部分取代。这些化合物显示出对脑啡肽酶的良好抑制能力，与类似物相比，对ACE而言，Ki值在亚微摩尔范围内的几种类似物。在一系列[（N-酰基氨基）甲基]膦酰胺盐中，由于N-酰基部分被更大，更疏水的酰基取代，对脑啡肽酶的抑制活性急剧下降。同样 较大的苯基烷基酰基官能度减弱了[（N-酰基氨基）甲基]膦酰胺酸盐对ACE的抑制活性，尽管程度与对脑啡肽酶的抑制程度不同。但是，（Leu）脑啡肽和（D-Ala2，D-Leu5）脑啡肽的膦酰胺五肽类似物显示出对两种酶的良好抑制能力。有趣的是，这两种（Leu）脑啡肽磷酸亚酰胺类似物在电刺激的豚鼠回肠和小鼠输精管的制备中完全没有活性。讨论了可能

  The effectiveness of phosphonamidate peptide analogues as inhibitors of rat kidney or human brain metalloendopeptidase (enkephalinase, E.C. 3.4.24.11) and angiotensin-converting enzyme (ACE, 3.4.14.1) has been explored with a series of enkephalin analogues in which the scissile Gly3-Phe4 amide bond has been replaced with a phosphonamidate moiety. These compounds exhibited good inhibitory potency against

  日期：2000.11.1

  A series of phosphonochloridates and phosphonyl dichlorides were prepared, and their reactivity with triethylamine has been investigated using P-31 NMR spectroscopy, Taken together these studies provide evidence that an intramolecular hydrogen-bond is required for phosphonylammonium salt formation to render the phosphorus more electron-deficient.
