  Regioselective Condensation of Alkylidenephosphoranes to N-Methoxy- and N-Anilino-1H isoindole-1,3-(2H)-diones

  摘要：

  Treatment of 2-methoxyisoindoline-1,3-dione with resonance-stabilized alkylidenephosphoranes afforded the corresponding monoalkenes as the sole reaction product, in similar to 58-63% yields, whereas more than 80% yields of the same monoolefin products were obtained when the reactions were carried out under microwave conditions. Similarly, 2-(phenylamino)isoindoline-1,3-dione reacted under either thermal or microwave conditions to give only the corresponding monoalkene derivatives. The alkene products from both substrates were further reduced to the corresponding isoindoles using Zn-dust in EtOH. Prediction of the designed compounds and the in vivo anti-inflammation activity of the products in the rat adjuvant model were also studied. The work is the first demonstration of the anti-inflammatory activity of phthalimide derivatives.

  through a highly efficient and E-selective C–H activation/Heck/Aza-Wacker sequence. Substoichiometric amounts of benzoquinone can be employed in a cooperative oxidation system with O2, leading to facile purification of products. Modification of the reaction conditions provides a general route to substituted phthalimides by carbonylation with CO. Both systems were found to tolerate a wide range of functionality

  提出了一种新的钯（II）催化方法，用于从N-烷氧基苯甲酰胺直接合成亚烷基异吲哚满酮。异吲哚啉酮的形成通过高效的E选择性C–H活化/ Heck / Aza-Wacker序列进行。亚化学计量的苯醌可以与O 2一起在协同氧化系统中使用，从而可以轻松纯化产物。反应条件的改变为通过CO羰基化取代苯二甲酰亚胺提供了一条通用途径。发现这两种体系都可以耐受广泛的功能。

  Herein, using electron-deficient alkenes embedded with an oxidizing function/leaving group as a rare and nontraditional C1 synthon, we have achieved the redox-neutral Rh(III)-catalyzed chemo- and regioselective [4 + 1] annulation of benzamides for the synthesis of functionalized isoindolinones. This method features broad substrate scope, good to excellent yields, excellent chemo- and regioselectivity
