  摘要：

  A new nickel catalyzed cross‐electrophile coupling for accessing γ‐lactams (isoindolinones) as well as γ‐lactones (isobenzofuranones) via carbonylation with CO2 is documented. The protocol exploits the synergistic role of redox‐active Ni(II) complexes and AlCl3 as a CO2 activator/oxygen scavenger, leading to the formation of a wide range of cyclic amides and esters (28 examples) in good to high yields (up to 87%). A dedicated computational investigation revealed the multiple roles played by AlCl3. In particular, the simultaneous transient protection of the pendant amino group of the starting reagents and the formation of the electrophilically activated CO2‐AlCl3 adduct are shown to concur in paving the way for an energetically favorable mechanistic pathway.

  An electrochemical protocol for the construction of substituted isoindolinones via reduction/amidation of 2-carboxybenzaldehydes and amines has been realized. Under metal-free and external-reductant-free electrolytic conditions, the reaction achieves the cascade formation of intermolecular C–N bonds and provides a series of isoindolinones in moderate to good yields.

  A direct one-pot synthetic approach is described wherein cobalt(ii) phthalocyanine (CoPc) catalyzed reductive amination of 2-carboxybenzaldehyde, followed by intramolecular amidation afforded N-substituted isoindolinones. The method used diphenylsilane as reducing agent in ethanol. High chemoselectivity with excellent yield was obtained in most of the studied substrates.

  AlCl3 has been employed for highly chemoselective reductive amination of carbonyl compounds in ethanol using polymethylhydrosiloxane as an inexpensive, stable and safe reducing agent without an inert atmosphere. A large range of functional groups such as nitro, carboxylic acid, acetyl, nitrile, halogen, methoxy, alkene and heterocycles were well tolerated. AlCl3 also catalyzed tandem amination–amidation

  AlCl 3已用于使用聚甲基氢硅氧烷作为廉价，稳定和安全的还原剂，在无惰性气氛的情况下对乙醇中的羰基化合物进行高度化学选择性的还原胺化反应。很好地耐受了各种官能团，例如硝基，羧酸，乙酰基，腈，卤素，甲氧基，烯烃和杂环。AlCl 3还催化2-羧基苯甲醛与不同的胺进行串联胺化-酰胺化反应，得到N-取代的异吲哚满酮。该催化剂可以循环至少三遍，而对活性和选择性没有任何明显的影响。
