Concise Synthesis of Spiro[indoline-3,2′-pyrrolidine] and 1-Azacarbazole Derivatives via Copper-Catalyzed Cyclization of Indoles

A high-yielding, copper-catalyzed dearomatization reaction of indole from 2-methylindole-derived oxime acetates was realized, providing access to structurally novel spiro[indoline-3,2′-pyrrolidine] derivatives in 67–98% yields. When the C-2 position of the indole was not substituted, azacarbazole derivatives were obtained in moderate yields. This transformation provides an efficient approach to access nitrogen-containing spiroindolenine and azacarbazole derivatives with wide substrate scope. (Figure presented.).

The invention discloses a synthesis method of 9H-pyridino[2,3-b]indole compounds, belonging to the technical field of organic synthesis. The technical scheme is as follows: the synthesis method comprises the following steps: dissolving 1-bromo-2-(2,2-dibromovinyl)benzene or derivatives thereof, ammonia water and alpha,beta-unsaturated aldehyde compounds in an organic solvent, adding a catalyst transition metal salt and an additive, and reacting at 60-100 DEG C in the presence of air to obtain the 9H-pyridino[2,3-b]indole compounds. The synthesis process is one-pot multicomponent series reaction, is simple to operate, avoids waste of resources and environmental pollution caused by the use of multiple reagents in multiple reaction steps, the purification treatment on the intermediate in each reaction step and the like, and provides an economical, practical, green and environment-friendly novel method for synthesizing the 9H-pyridino[2,3-b]indole compounds.

An efficient synthesis toward highly diversified α-carboline derivatives via a three-component tandem reaction using acid chlorides, terminal alkynes, and 2-aminoindole hydrochlorides has been described. The salient feature of the one-pot strategy involve

Thermal rearrangement of indolyl oxime esters to pyridoindoles

(Chemical Equation Presented) Acyl oximes derived from a variety of indolylalkanones underwent a ring closure sequence during FVP to afford 9H-pyrido[2,3-b]indoles. Unlike UV light promoted reactions of oxime esters, the mechanism is almost certainly not mediated by iminyl radicals but probably involves tautomerism, elimination of acetic acid, and a final electrocyclic ring closure.

An alternative approach to the synthesis of functionalized pyrido[2,3-b]indoles

A new synthesis of α-carbolines was developed starting from the easily accessible 3-substituted indol-2(3H)-one derivatives 2 and enamines 3. The intermediates 4 afforded the α-carbolines 5 and 6 by thermal cyclization with ammonium acetate in glacial acetic acid by way of pyridine ring formation.
