  2-烷氧基-4-氨基-N-[(4-苄基-2-吗啉基)甲基]-5-氯苯甲酰胺已被确定为一系列选择性强效胃动力药的有趣成员。我们合成了一系列新的 2-氨基-和 2-（取代氨基）-N-[（4-苄基-2-吗啉基）甲基]苯甲酰胺（13-35），并对这些化合物进行了研究，以确定它们与带有 2-烷氧基的 2-吗啉基苯甲酰胺 1 相比是否具有优势。胃动力活性普遍降低，但有几个化合物显示出相对较强的活性，可与标准药物甲氧氯普胺相媲美。N-[(4-Benzyl-2-morpholinyl)methyl]-4-chloro-2-[(4-chlorobenzoyl)amino]benzamide (32) 在该系列中显示出最强的活性。

  Copper catalyzed CN bond formation/C–H activation: synthesis of aryl 4H-3,1-benzoxazin-4-ones

  摘要：

  We have developed a practical and efficient synthesis of 2-phenyl-4H-benzo[d][1,3]oxazine-4-one derivatives through copper catalyzed tandem reaction of 2-iodobenzoic acid with arylmethanamines under aerobic conditions. Compared to the literature methods toward the synthesis of 2-phenyl-4H-benzo[d][1,3]oxazine-4-one, the synthetic method reported in this Letter has broad substrate scope, mild reaction condition, and uses an inexpensive catalyst.

  copper-catalyzed reduction of phosphine oxide was used and found effective for this transformation. Additionally, the one-pot catalytic aza-Wittig reaction of carboxylic acids was achieved. Furthermore, NMR experiments and Hammett plot recorded the process of catalytic aza-Wittig reaction of anhydride, which provides direct proof that the copper-catalyzed reduction of waste phosphine oxide is the key step

  与醛，酮，酰胺和酯的aza-Wittig反应相比，酸酐的aza-Wittig反应总是被忽略，这应该是Wittig反应的重要组成部分。在这里，酸酐的aza-Wittig反应和酸酐的aza-Wittig催化反应均以高收率开发，这为合成4 H-苯并[ d ] [1,3]恶嗪-4-酮和4-亚苄基-2-芳基恶唑-5（4 H）-那些。使用了铜催化的氧化膦还原的策略，发现该策略对这种转化有效。另外，实现了羧酸的一锅催化的氮杂-维蒂希反应。此外，NMR实验和Hammett曲线记录了酸酐的催化氮杂-维蒂希反应过程，这直接证明了铜催化的废氧化膦的还原是该转化过程中的关键步骤。

  cyclisation of 2-aminobenzoic acids and arylaldehyde using I2 as a catalyst and an environmentally benign oxidant oxone. This method displays facile access to a diverse range of substituted aryl 4H-3,1-benzoxazin-4-ones. This synthetic methodology has many advantages such as: (1) easy availability of starting material, (2) transition metal-free condition (3) use of an environmentally benign oxidant.

  2-Alkoxy-4-amino-N-[(4-benzyl-2-morpholinyl)methyl]-5-chlorobenzamides had been identified as the interesting members of a series of selective and potent gastroprokinetic agents. A new series of 2-amino- and 2-(substituted amino)-N-[(4-benzyl-2-morpholinyl)methyl]benzamides (13-35) has been synthesized and these compounds were examined to determine whether they have advantages over the 2-morpholinyl benzamides 1 with a 2-alkoxy group.The gastroprokinetic activity was generally reduced, but several compounds showed relatively potent activity, comparable to that of the standard agent, metoclopramide. N-[(4-Benzyl-2-morpholinyl)methyl]-4-chloro-2-[(4-chlorobenzoyl)amino]benzamide (32) showed the most potent activity in this series.
