  Preparation of N-substituted phthalimides by the palladium-catalyzed carbonylation and coupling of o-dihalo aromatics and primary amines

  摘要：

  A novel method for the formation of N-substituted phthalimides is described which is based on the palladium-catalyzed carbonylation and coupling of o-dihalo aromatics and primary amines. Optimal conditions established for the reaction using o-diiodobenzene and aniline were DMAc (0.2 M), 115-degrees-C, 90 psi of CO, 3% PdCl2L2, and 2.4 equiv of DBU. This process is tolerant of a wide variety of functional groups and gives good yields of the desired products. Variables such as temperature, catalyst type and loading, CO pressure, solvent, and base were examined to optimize this reaction. The reaction of aniline with 1,2-dibromocyclopentene under similar conditions gave a variety of products.

• Unmasking Amides: Ruthenium-Catalyzed Protodecarbonylation of N-Substituted Phthalimide Derivatives

  The unprecedented transformation of a wide range of synthetically appealing phthalimides into amides in a single-step operation has been achieved in high yields and short reaction times using a ruthenium catalyst. Mechanistic studies revealed a unique, homogeneous pathway involving five-membered ring opening and CO2 release with water being the source of protons.

  A rhodium(III)‐catalyzed amidation between benzoic acids and isocyanates via direct functionalization of an ortho CH bond followed by intramolecular cyclization is described. This cascade cyclization affords N‐substituted phthalimides in one step in 26–91% yields. The reaction is highly atom‐economical, since no theoretical waste except for water is generated in the reaction.

  We report on cyclic imides as weak directing groups for selective monohydroxylation reactions using ruthenium catalysis. Whereas acyclic amides are known to promote the hydroxylation of the C(sp2)–H bond enabling five-membered ring ruthenacycle intermediates, the cyclic imides studied herein enabled the hydroxylation of the C(sp2)–H bond via larger six-membered ruthenacycle intermediates. Furthermore

  我们报告了环状酰亚胺作为使用钌催化的选择性单羟基化反应的弱导向基团。已知无环酰胺可促进C（sp 2）-H键的羟基化，从而形成五元环钌环中间体，而本文研究的环酰亚胺可通过较大的六元环实现C（sp 2）-H键的羟基化。钌循环中间体。此外，仅获得单羟基化产物（即使在化学计量过量的试剂存在下），这是由于一旦将第一个羟基引入底物中就难以容纳共面中间体而合理化。在钯催化剂的存在下观察到相同的反应性。

  An efficient and facile protocol for the synthesis of biologically and pharmaceutically important phthalimides is developed by l-proline-catalyzed reaction between two dienophiles of α,β-unsaturated aldehydes and maleimides. The reaction involves an efficient benzannulation that proceeds via a formal [4 + 2] cycloaddition of azadiene intermediates generated in situ from enals and N-substituted maleimides
