  日期：——

  N-monomethylation of amines is an important topic in fine chemical synthesis. Herein, for the first time, we described a selective N-monomethylation reaction of amines with paraformaldehyde and H2 in the presence of a CuAlOx catalyst. A variety of amines, including primary aromatic amines, benzylamine and cyclohexylamine, as well as secondary amines, have been shown to be compatible with this reaction.

  A series of new N-phenylbenzamido acid derivatives was synthesized and evaluated for their ability to inhibit the IgE-mediated passive cutaneous anaphylaxis in the rat (PCA), as well as for their capacity to inhibit gastric mucosal damage induced by the oral administration of absolute alcohol in the rat. Some of these new derivatives exhibit potent antiallergic and cytoprotective activity, 20-80 times

  into the C−N bond of amines are reported. Using low‐valent iron complexes, including K2[Fe(CO)4], amides are formed from aromatic and aliphatic amines, in the presence of an iodoalkane promoter. Inorganic Lewis acids, such as AlCl3 and Nd(OTf)3, have a positive influence on the catalytic activity of the iron salts, enabling the carbonylation at a low pressure of CO (6 to 8 bars).

• Asymmetric α-arylation of amino acids
  作者：Daniel J. Leonard、John W. Ward、Jonathan Clayden

  DOI：10.1038/s41586-018-0553-9

  日期：2018.10

  α-aryl amino acids and their derivatives are valuable precursors to bioactive molecules10,11. Here we describe the synthesis of quaternary α-aryl amino acids from enantiopure amino acid precursors by α-arylation without loss of stereochemical integrity. Our approach relies on the temporary formation of a second stereogenic centre in an N′-arylurea adduct12 of an imidazolidinone derivative6 of the precursor

  季氨基酸，其中带有氨基和羧基的 α-碳也带有两个碳取代基，作为肽构象和生物活性的修饰剂以及作为药用重要化合物的前体具有重要作用 1,2。与在该 α-碳上的对映选择性烷基化（有多种方法 3-8）相比，在 α-碳上一般对映选择性引入芳基取代基在合成上具有挑战性 9。尽管如此，由此产生的 α-芳基氨基酸及其衍生物是生物活性分子 10,11 的有价值的前体。在这里，我们描述了通过 α-芳基化从对映纯氨基酸前体合成季 α-芳基氨基酸而不损失立体化学完整性。我们的方法依赖于在前体氨基酸的咪唑啉酮衍生物 6 的 N'-芳基脲加合物中临时形成第二个立体中心，并使用容易获得的对映体纯氨基酸作为前体和不对称的来源。它避免使用有价值的过渡金属，并能够用富电子、贫电子和杂环取代基进行芳基化。产物的任一对映异构体都可由单一氨基酸前体形成。该方法实用且可扩展，并提供了生产数克数量的 α-芳基化季铵氨基酸的机会。该方法
