  一种α-萘乙酸的制备方法

  摘要：

  本发明涉及有机合成技术领域，针对制备α‑萘乙酸不经济环保的问题，本发明提供一种α‑萘乙酸的制备方法，包括以下步骤：（1）将萘和路易斯酸溶于溶剂中，升温后加入草酰氯单酯反应生成α‑萘乙酮酸酯；（2）先将步骤（1）得到的α‑萘乙酮酸酯和水合肼加入高沸点醇溶剂中加热反应，再加入强碱继续升温反应，反应结束后调pH至酸性得到α‑萘乙酸。本发明以价廉易得的萘和草酰氯单酯为原料，在路易斯酸作用下制备萘乙酮酸酯，然后经水合肼作用发生一系列反应，生成α‑萘乙酸，避免了使用剧毒品氰化物，反应过程中不产生剧毒或恶臭气体，产物单一，反应条件温和、收率高、成本低。

• Copper-catalyzed Pummerer type reaction of α -thio aryl/heteroarylacetates: Synthesis of aryl/heteroaryl α -keto esters

  日期：2017.5

  A copper catalyzed Pummerer type reaction of α-thio aryl/heteroarylacetates is described for the first time. This transformation represents a new route to synthesize α-keto esters, which are important intermediates for pharmaceuticals and organic synthesis. The reaction proceeds via in situ generation of a thionium ion that undergoes hydrolysis to furnish α-keto esters in synthetically viable yields

  Carbene transfer reactions play an important role in the field of organic synthesis because of their ability to construct a variety of molecules. Herein, we reported on blue light-induced cyclopropenizations of N-tosylhydrazones in water, which avoids the use of expensive metal-based catalysts and toxic organic solvents. This metal-free and operationally simple methodology enable highly efficient cyclopropenizations

  A direct catalytic asymmetric addition of acetonitrile to aldehydes that realizes over 90 % ee is the ultimate challenge in alkylnitrile addition chemistry. Herein, we report achieving high enantioselectivity by the strategic use of a sterically demanding NiII pincer carbene complex, which afforded highly enantioenriched β‐hydroxynitriles. This highly atom‐economical process paves the way for exploiting
