Abstract
The synthesis of 2,3-dihydropyrazino[1,2-a]indol-4(1H)-ones from the sequential reaction of amino acid methyl esters with readily available indole-2-ylmethyl acetates is described. The reaction proceeds in situ under basic conditions of highly unstable and reactive 2-alkylideneindolenines followed by Michael-type addition of α-amino acid methyl esters/intramolecular cyclization. The synthesis of 2,3-dihydropyrazino[1,2-a]indol-4(1H)-ones through the in situ generation of 2-methide-2H-indole intermediate I starting from 2-indolylmethyl acetates under basic conditions/nucleophilic Michael addition/cyclization cascade reaction.![]()

Abstract
This review concerns the synthesis and biological activities of pyrazino[1,2-a]indoles and pyrazino[1,2-a]indol-1-ones reported since 1997 and the discovery of biological activity of pyrazinoindole derivatives. In the first part, we first presented the synthetic routes that have been reported from a methodological point of view to access the pyrazinoindole unit according to cyclization reactions using or not using metal catalysts. Then, syntheses and neuropsychiatric, auto-immune, anti-infectious and anti-cancer properties of pyrazinoindoles were detailed. In the second part, we first reported the main accesses to pyrazinoindol-1-one substrates according to Michael reactions, metal-catalyzed and metal-free cyclization reactions. The syntheses and anti-cancer, anti-infectious, anti-allergenic and neuropsychiatric properties of pyrazinoindolones were next described and discussed.

Abstract
Abstract
Pyrazino[1,2-a]indoles fused with various heterocycles, such as oxazolidine, oxazinane, imidazolidine, hexahydropyrimidine and benzimidazole, were synthesized transition metal-free by domino reactions which involved the condensation of 1-(2-bromoethyl)-3-chloro-1H-indole-2-carbaldehydes 28–31 with various nucleophilic amines, resulting in the formation of two new interesting fused heterocycles. The anticholinesterase, antioxidant and antibacterial activities of the compounds were evaluated. Acetylcholinesterase (AChE) inhibitory activities were tested by Ellman’s assay, antioxidant activities were detected using the 2,2-azinobis[3-ethylbenzthiazoline]-6-sulfonic acid (ABTS•+) free-radical scavenging method and antibacterial activities were determined by agar diffusion tests. The oxazolo-pyrazino[1,2-a]indoles (8, 10), the oxazino-pyrazino[1,2-a]indoles (16, 18, 19), the pyrimido-pyrazino[1,2-a]indole (22), and the benzoimidazo-pyrazino[1,2-a]indole (27) possessed the highest inhibitory activity against AChE with IC50 values in the range 20–40 μg mL−1. The oxazolo-pyrazino[1,2-a]indoles (8, 9), the imidazo-pyrazino[1,2-a]indoles (12, 13), and the benzoimidazo-pyrazino[1,2-a]indole (24) revealed the highest antioxidant values with IC50 values less than 300 μg mL−1. However, the oxazolo-pyrazino[1,2-a]indole (11) and imidazo-pyrazino[1,2-a]indoles (12, 13) exhibited weak to moderate bioactivities against all tested Gram-positive bacteria, namely Staphylococcus aureus, Bacillus subtilis and Bacillus cereus.

Abstract
Here we describe a facile, tandem synthetic route for indolo[3,2-c]quinolinones, a class of natural alkaloid analogues of high biological significance. A Ugi four-component reaction with indole-2-carboxylic acid and an aniline followed by a Pd-catalyzed cyclization yields tetracyclic indoloquinolines in good to moderate yields. Commercially available building blocks yield highly diverse analogues in just two simple steps.

Abstract
Substituted 1H-pyrazolo[3,4-b]pyridine-4- and 1H-pyrazolo[3,4-b]pyridine-6-carboxamides have been synthetized through a Doebner-Ugi multicomponent reaction sequence in a convergent and versatile manner using diversity generation strategies: combination of two multicomponent reactions and conditions-based divergence strategy. The target products contain as pharmacophores pyrazolopyridine and peptidomimetic moieties with four points of diversity introduced from readily available starting materials including scaffold diversity. A small focused compound library of 23 Ugi products was created and screened for antibacterial activity.
