  Nucleophilic reactions of molybdate

  摘要：

  Although molybdate (MoO42-) is over 1000 times less basic than the phosphate dianion it is 35 times more nucleophilic toward p-nitrophenyl acetate (pNPA) and p-nitrophenyl thioacetate (pNPTA) at 27-degrees-C (Wikjord, B.; Byers, L. D. J. Am. Chem. Soc. 1992,114,5553). Based on Bronsted relationships for the reaction of a series of phosphonate dianions with these esters (beta(nuc) = 0.3 at 37-degrees-C), molybdate (pK(a2) = 3.9) is as reactive as a phosphonate with pK(a2) = 12. The activation parameters are DELTAH(double dagger) = 15.8 (+/-0.1) kcal/mol and DELTAS(double dagger) = -17.4 (+/-0.4) eu for the reaction with pNPA and DELTAH(double dagger) = 16.0 (+/-0.2) kcal/mol and DELTAS(double dagger) = -15.0 (+/-0.6) eu for the reaction with pNPTA. The second-order rate constant for the reaction of MoO42- with a series of 13 acyl-substituted p-nitrophenyl esters at 27-degrees-C shows nearly identical sensitivity to substituent effects (rho* = 2.8) as does the rate of alkaline hydrolysis or the equilibrium addition of hydroxide to aldehydes (Shames, S. L.; Byers, L. D. J. Am. Chem. Soc. 1981, 103, 6170), suggesting that the transition state for the molybdenolysis reaction closely resembles the tetrahedral intermediate. In addition to the reaction with activated carboxylic esters, molybdate catalyzes the hydrolysis of a variety of electrophiles. The second-order rate constants (M-1 min-1, 27-degrees-C, mu = 1.5 M) for the reactions of molybdate are 0.25 (+/-0.01) with ethyl pyruvate, (2.10+/-0.08) x 10(-2) with 2,4-dinitrofluorobenzene, and (7.2 +/-0.4) x 10(-5) with methyl iodide.

  has been developed for the enantioselective synthesis of α-amino acid derivatives containing two stereogenic centers from readily accessible N,N-disubstituted glycine aryl esters and allylic phosphates. The optimized process uses a bench-stable succinimide-based Pd precatalyst (FurCat) to promote Pd-catalyzed allylic ammonium salt generation from the allylic phosphate and the glycine aryl ester.

  We recently reported the use of PSCl3 for the thiophosphorylation of alkylamines where the resulting N-thiophosphoramidate ions could be readily S-alkylated (Chem. Commun., 2011, 47, 6156–6158.). Herein we report the development of this methodology using amino acid, amino sugar, aminonucleoside and aniline substrates. The hydrolysis properties of N-thiophosphoramidate ions and their reactivities towards alkylating agents are also explored. In addition, we demonstrate the application of our approach to the preparation of a small library of compounds, including quinoline-based N,S-dialkylthiophosphoramidates which were tested for antileishmanial activity.

  我们最近报道了使用PSCl3对烷基胺进行硫代膦酰化反应，得到的N-硫代膦酰胺离子可以容易地进行S-烷基化（《化学通讯》，2011年，第47卷，第6156-6158页）。在此，我们报道了利用氨基酸、氨基糖、氨基核苷和苯胺底物开发这种方法。研究了N-硫代膦酰胺离子的水解性质及其对烷基化剂的反应活性。此外，我们还展示了该方法在制备小规模化合物库中的应用，其中包括了用于抗利什曼活性测试的喹啉基N,S-二烷基硫代膦酰胺。

Cyclic and acyclic nitrogen substituents as well as various aromatic substituents are tolerated,

  Functionalized α‐arylamino‐α′‐chloro ketones are obtained in high yield via a straightforward homologation reaction of Weinreb amides derived from N‐arylglycines using in situ generated chloromethyllithium. The use of the Weinreb amides is essential and allows the chemoselective homologation of N‐aryl‐N‐substituted glycine analogues, a transformation which is not possible using similar glycine esters. The

  通过使用原位生成的氯甲基锂通过N-芳基甘氨酸衍生的Weinreb酰胺的直接同系物反应，可以高收率获得功能化的α-芳基氨基-α'-氯酮。Weinreb酰胺的使用是必不可少的，它可以实现N-芳基-N-取代的甘氨酸类似物的化学选择性同源性，而使用类似的甘氨酸酯则无法实现这种转化。该方法有望大规模制备α-氨基-α'-氯丙烷，α-氨基-α'-氯丙烷是多种生物活性化合物的宝贵前体。

  Calcium oxide is proposed as an innocuous acid scavenger for the chemoselective synthesis of amide‐ and ester‐type compounds. Although these molecules have wide spread applications in organic and pharmaceutical chemistry, and a large number of routes have been designed for their synthesis, the development of more efficient and environmentally friendly acylation strategies remains an ongoing challenge

  氧化钙被提议作为酰胺和酯类化合物化学选择性合成的无害酸清除剂。尽管这些分子在有机和药物化学中具有广泛的应用，并且已经设计了许多合成途径，但是开发更有效和对环境友好的酰化策略仍然是一项持续的挑战。CaO的使用允许在酚或叔醇存在下伯醇的化学计量酰化；胺还可以在羟基存在下进行酰化反应。如果起始原料是光学纯的醇或使用手性酰化剂，则通过酰化获得手性。此外，使用更环保的溶剂2-甲基四氢呋喃（2-MeTHF），导致产量最大化。该协议已成功应用于有趣的综合N-芳基恶唑烷-2-酮中间体，用于制备利奈唑胺类化合物。
