  Metal-Free Intramolecular Amination: One-Pot Tandem Synthesis of 3-Substituted 4-Quinolones

  摘要：

  3-Substituted 4-quinolones were synthesized using a one-pot metal-free strategy in moderate to quantitative yields. Carried out in dimethylsulfoxide (DMSO) via a sequential addition of materials, the methodology is tolerant of a wide range of functional groups and applicable to library synthesis.

  efficient strategy for the synthesis of isocoumarins and phthalides through a palladium(0)-catalyzed reaction incorporating tert-butyl isocyanide has been developed. This process, providing one of the simplest methods for the synthesis of this class of valuable lactones, involves two steps including cyclization reaction and simple acid hydrolysis. The methodology is tolerant of a wide range of substrates

  novel nickel catalyst for the reaction of tert-butyl isocyanide insertion was discovered. In this approach, 1,2-bis(diphenylphosphino)ethane (L3) serves as an efficient ligand, thereby allowing the preparation of lactones from (o-bromophenyl)phenylethanone derivatives. It is noteworthy that this is the first example of nickel acting as a metal catalyst in the reactions of tert-butyl isocyanide insertion

  摘要 发现了一种用于叔丁基异氰化物插入反应的新型镍催化剂。在这种方法中，1,2-双（二苯基膦基）乙烷（L3）作为一种有效的配体，从而允许从（邻溴苯基）苯基乙酮衍生物制备内酯。值得注意的是，这是镍在叔丁基异氰化物插入反应中作为金属催化剂的第一个例子。这种方法的重要性可能会引起异氰化物掺入反应领域许多化学家的注意。[本文提供补充材料。访问出版商的 Synthetic Communications® 在线版，获取以下免费补充资源：完整的实验和光谱细节。] 图形摘要

  Isoflavone derivatives were synthesized via intramolecular cyclization of 3‐(2‐bromophenyl)‐3‐oxopropanal derivatives, using CuI as the catalyst, 2‐picolinic acid (=pyridine‐2‐carboxylic acid) as the ligand, K2CO3 as the base, and DMF as the solvent, in up to 96% yield. The synthesis is functional group‐tolerant.
