  具有受阻叔β-氨基酰胺立体中心的强效CXCR7调节剂的不对称合成

  摘要：

  报道了实用化和不对称合成的小分子CXCR7调节剂，其特征是高度官能化且受阻的叔β-氨基酰胺骨架。该策略的基础是反应性叠氮化合物的中间产物，在用氰化物进行区域选择性开环后，该叠氮化合物提供了所需的手性β-叔氨基腈用于进一步的精制。作为进一步强调该合成策略的一种手段，还介绍了受阻β-氨基酰胺合成的扩大范围。

  [PAIM][NTf]/BMIM-ILs as a base/solvent in the Corey-Chaykovsky reaction is demonstrated by the facile synthesis of libraries of functionalized cyclopropanes from enones and oxiranes from aldehydes and ketones, at room temperature in respectable isolated yields. To demonstrate their application, the synthesized epoxides were employed as substrates for the synthesis of a library of 2,3-disubstituted quinolines, using

  Provided is a modified ethylene-vinyl alcohol copolymer (C) having an ethylen content of 5 to 55 mol %, which contains a specific structural unit (I) in an amount of 0.3 to 40 mol % and may be obtained by reacting an ethylene-vinyl alcohol copolymer (A) with a monofunctional epoxy compound (B) having a molecular weight of not more than 500. This can be produced by a method for producing the modified ethylene-vinyl alcohol copolymer (C) which comprises melting and kneading an ethylene-vinyl alcohol copolymer (A) with a monofunctional epoxy compound (B) in an extruder. The modified ethylene-vinyl alcohol copolymer (C) is superior to a unmodified ethylene-vinyl alcohol copolymer (A) in transparency, stretchability, flexibility and flexing resistance due to the specific structural unit (I) incorporated therein, and thus, can be used as a barrier material in various applications requiring the above performance capabilities.
