Maleimide and succinimide core moieties are present in various natural products and pharmaceuticals. In addition, these derivatives can be readily modified into biologically important organic molecules including pyrrolidines and γ-lactams. A transition-metal-catalyzed chelationassisted functionalization of inert CÀ H bond of organic molecules with electrophiles or nucleophiles is one of the efficient methods to construct chemical bonds in a highly atom-and step-economical manner. The present review describes the recent advances in the reaction involving maleimides with organic molecules by a chelation-assisted inert CÀ H bond activation methodology. The reaction involving maleimides with organic molecules having directing groups, such as ketone, acyl, pyridyl, pyrimidyl, oxime, amide, imidate, chromone, azo, N-sulfonyl ketimine, carboxylic acids, and aldimines, were described. The scope, limitation and mechanistic investigation of the alkylation, annulation and alkenylation reactions were discussed elaborately. This review article includes the entire report on the chemical bondforming reaction of maleimides with organic molecules by the CÀ H bond activation strategy until the end of 2018.

“…Cyclic imines are of prime importance as they could lead to the formation of spirocompounds via a [3 + 2] annulation reaction. In 2016, Kim described The Rh(III)-catalyzed redox-neutral coupling process of N-acyl ketimines generated in situ from 3-hydroxyisoindolinones with a wide range of activated olefins (Scheme 48) [147]. This approach led to the synthesis of bioactive spiroisoindolinone derivatives in good yields.…”

Rh(III)-catalyzed C–H activation features mild reaction conditions, good functional group tolerance, high reaction efficiency, and regioselectivity. Recently, it has attracted tremendous attention and has been employed to synthesize various heterocycles, such as indoles, isoquinolines, isoquinolones, pyrroles, pyridines, and polyheterocycles, which are important privileged structures in biological molecules, natural products, and agrochemicals. In this short review, we attempt to present an overview of recent advances in Rh(III)-mediated C–H bond activation to generate diverse heterocyclic scaffolds with sp3 carbon centers.

“…(3)]. [117] It was found that olefins of maleimides, maleates, fumarates, and cinnamates led to the formation of spiroindane products via the [3+ +2] annulation, while acrylates and quinones furnished unsaturated spiroindene products resulting from b-H elimination ands ubsequent Prins-typecyclization.…”

“…Very recently, a rhodium‐catalyzed [3+2] annulation of N ‐acyl ketimines with various activated olefins is described by the Kim group [Eq. (3)] . It was found that olefins of maleimides, maleates, fumarates, and cinnamates led to the formation of spiroindane products via the [3+2] annulation, while acrylates and quinones furnished unsaturated spiroindene products resulting from β‐H elimination and subsequent Prins‐type cyclization.…”
