摘要以可磁循环GO / Fe 3 O 4 -CuI为催化剂,通过卤化物苯甲酰胺与氨基酸的缩合反应,有效合成了一系列生物活性喹唑啉酮。通过简单的化学方法制备了磁性GO / Fe 3 O 4 -CuI,并通过FTIR,粉末XRD和SEM对其进行了表征。这种多相铜催化剂可以很容易地通过外部永磁体从反应混合物中分离出来,并且可以在没有任何明显活性降低的情况下重复使用,这表明其可作为可重复使用的有前途的喹唑啉酮合成催化剂。
A straightforward and general method has been developed for the synthesis of phthalimide derivatives from 2-iodobenzamides and PPh3/I2/HCOOH in the presence of a catalytic amount of Pd(OAc)2. The reaction results demonstrate that PPh3/I2/HCOOH is a facile, efficient and safe CO source. The whole process is carried out in toluene at 80 °C and furnishes the desired products in good to excellent yields
已经开发了一种简单且通用的方法,用于在催化量的Pd(OAc)2存在下由2-碘联苯甲酰胺和PPh 3 / I 2 / HCOOH合成邻苯二甲酰亚胺衍生物。反应结果表明,PPh 3 / I 2 / HCOOH是一种简便,高效,安全的CO源。整个过程在80°C的甲苯中进行,并以优异的产率提供了所需的产品。

Imido transfer of sulfonylimino-λ3-bromane makes possible the synthesis of sulfonylimino-λ3-iodanes
Sulfonylimino-λ3-bromane functions as a reactive nitrenoid, because of the hyperleaving group ability of aryl-λ3-bromanyl groups, and undergoes transimidations to iodobenzenes at room temperature under metal-free conditions probably via an SN2-type nitrenoid transition state, yielding sulfonylimino-λ3-iodanes.

A direct double functionalization involving both difluorination and hydroxylation of enamides is reported. With the appropriate combination of an electrophilic fluorinating reagent and H2O, the most convenient and ecofriendly hydroxylating agent, the preparation of 3-(difluoroalkyl)-3-hydroxyisoindolin-1-ones was achieved under basic or Brønsted acidic conditions. Suitable conditions for trifluorination
