The synthesis of indolines from indoles by hydrogenation is not an easy task, since the indole nucleus is highly stabilized by resonance, in addition to the possibility that the formed indoline, a cyclic secondary amine, could poison the metal catalyst, thus preventing the reaction to succeed.
This chapter of the book in Advances in Synthetic Organic Chemistry features an important component of organic chemistry known as indoline. The chemical agents mentioned in the book are classified by both their functional group type and product utility designation. This makes it easier for the reader to look for a specific agent.Indoline and indole derivatives are ubiquitous in nat-ure as well as in compounds of pharmaceutical interest.1 Their preparation and functionalization are widely re-cognizedasaprivilegedfieldofinvestigation.2 Benzopyr-rolizidines represent an important subclass of this family ofheterocycles,encompassingforinstancethemitomycin.Synthesis of indoles. Indoles, dihydroisoquinolines, and dihydroquinolines were efficiently prepared by ruthenium-catalyzed heterocyclizations of aromatic homo- and bis-homopropargyl amines or amides in the presence of pyridine.

Indolines are aromatic bicyclic heterocycles consisting of a benzene ring fused to a five-membered nitrogen-containing ring. Indole alkaloids are extensively studied for their biological activities in several pharmaceutical areas, such as anticancer and antitumor. Among this chemical family, indolinone displays very promising antitumor properties by inhibiting various kinase families. These.

The Bartoli indole synthesis is an organic reaction where a substituted nitroarene is converted to an indole using an excess of a vinyl Grignard reagent followed by an acid work-up. The substituents on the nitroarene affect the yield of this reaction where the highest yields are observed for ortho substituted reagents and the bulkier groups usually result in higher yields.
