ABSTRACT: In this work, quinoline derivatives were synthesized from reaction of aniline, benzylaldehyde and dimethylacetylene dicarboxylate (DMAD) in sequent steps to provide quinoline derivative dimethyl (2R, 3S, 4R)-2-phenyl-4-(phenylamino)-1, 3, 4-trihydroquinoline-2,3-dicarboxylate (12). Compound (12), was reacted with some amines such as hydrazine hydrate, urea, thiourea, ethylenediamine, diaminopropane, dinitrophenylhydrazine and o-phenylenediamine to give (3aS,9R,9aS)-2-amino-3a-phenyl-9-(phenylamino)-4,9,9a-trihydro-pyrrolo[3,4-b]quinoline-1,3-dione (13), (3aR) - 1,3 – dioxo - 3a-phenyl-9-(phenylamino)-4,9,9a-trihydro-pyrrolo[3,4-b]quinoline-2-carboxamide (14), (3aS)-1,3-dioxo-3a-phenyl-9-(phenylamino)-4,9,9a-trihydro-pyrrolo[3,4-b] quinoline - 2-carbothioamide (15), 6a-phenyl-12-(phenylamino)-2,3,4,5,7,12,12a-heptahydro-[1,4]diazocino[6,7-b]quinoline-1,6-dione (16), (7aS)-7a-phenyl-13-(phenylamino)-2,3,4,5,6,8,13,13a-octahydro-[1,5]diazonino[7,8-b]quinoline-1,7-dione (17), 2-((2,4-dinitrophenyl)amino)-9-(phenylamino)- 4, 9, 9 a - trihydro-pyrrolo [3,4-b] quinoline-1,3-dione (18), and 2-(2-aminophenyl)-6a-phenyl-12-(phenylamino)-2, 4,5,7,12,12a-hexahydro-diazocino[3,4-b]quinoline-1,6- dione (19) respectively. Reaction of (12) sodium metal gave methyl 3-oxo-2-phenyl-5-(phenylamino)-1,2, 4,5-tetrahydro- benzo[b]azepine-4-carboxylate(20). These reactions were carried out with different solvents like acetonitrile, ethanol, and chloroform providing good yields of the new heterocyclic compounds (13-20) of quinoline derivatives. The identification of the compounds(13-20) were based on spectroscopic analysis such as IR, UV, 1H-NMR, 13C-NMR, and the microanalysis of the elements (CHN) data.

INTRODUCTION: In recent years, the chemistry of nitrogen heterocyclic compounds especially quinolines has attracted attention due to their reactivity and biological activities like antibacterial 1, antiasthmatic 2, antihypertensive 3, anti-inflammatory agents 4, and antiobesity. 5 Quinolines also have antipyretic, antiperiodic 6 properties and are used as antimalarials and for preparing other antimalarial drugs.7
Quinoline derivatives are prevalent in a variety of pharmacologically active synthetic and natural compounds. 8 A prominent example is quinine (1) which is found naturally in plants as alkaloids 9. The chloroquine (2) 10 is the most famous drug containing this active ingredient resulted in control and treatment of malaria for decades 7.
Because the chloroquine prevent the development of malaria parasites in the blood so it is used by doctors to both prevent and treat malaria. 11 Simple quinoles (3-6) are isolated from the bark of Galipea longiflora trees of the Rutaceae family 12-14 used effectively against the parasites Leishmania sp., which are the agents of Leishmaniasis, a protozoan disease of the tropical areas in South Africa, particularly in the amazonian forest.15 Previous publications have clearly demonstrated many reactions in various synthetic applications which give rise to quinoline nucleus. 16-19 The most versatile method available for the synthesis of quinoline derivatives is the reaction of 2-aminoacetophenon and ethyl acetoacetate in the presence of chloramine-T and acetonitrile as a solvent to afford (7). 20, 21
There is a facile and efficient iron-catalyzed intramolecular allylic amination of 2-aminophenyl-1-en-3-ols which proceeds smoothly to afford 1,2-dihydroquinoline and quinoline derivatives such as (8) and under further mild reaction conditions gives good yields of (9). 22 Also, 1,4-dihydroquinolines such as (11) has been reported through sequential N-acylamide (10) methylenation-enamide ring-closing metathesis. 23
As a part of our continued interest in the development of new synthetic methods for further highly substituted fused rings to quinoline nucleus, we have developed a new synthetic route mainly to the synthesize of pyrroloquinolines derivatives through unprecedented approach from dimethyl (2R,3S,4R)-2-phenyl - 4 - (phenylamino)-1,3,4-trihydroquinoline-2,3-dicarboxylate (12) and amines.
MATERIALS AND METHOD:
Infrared (IR) spectra were recorded on Shimadzu FT-IR 8400S instrument, and were calibrated using a polystyrene film. Solid compounds were recorded in potassium bromide disks (KBr).Ultraviolet (UV) spectra were recorded on Shimadzu UV-1800 spectrophotometer, 1H-NMR spectra were recorded on 400 MHz AV III-HD-800 Bio Spin spectrometer while 13C-NMR were recorded on 300 MHz Bruker spectrometer instrument using dimethyl sulfoxide (DMSO-d6) as a solvent solution, using tetramethylsilane (TMS) as an internal standard. Chemical shifts were quoted in parts per million (ppm) downfield from TMS. Elemental analysis was performed on the CHN elemental (Eur Vector EA 3000A) Germany, see Table 1. Analytical thin layer chromatography (T.L.C.) was carried out on already made 5x5 cm plates coated with silica gel 0.25 cm N-HR/UV254 , while column chromatography was carried out using silica gel (60-230 mesh) as a stationary phase and different solvent systems as mobile phases.

In view of significant interest in the synthesis of these heterocyclic, we herein report in a detailed account of the synthetic methods available for the synthesis of (12). In a typical experiment, aniline, dimethyl acetylenedicarboxylate (DMAD) and benzaldehyde were reacted in presence of p-toluene sulfonic acid in absolute ethanol with stirring to afford the corresponding product, dimethyl (2R,3S,4R)-2-phenyl-4-(phenylamino)- 1, 3, 4-tryhydroquinoline-2,3-dicarboxylate (12) in moderate yield. The reaction was completed within 72 hours, as it can be seen below:
The mechanism apparently do not differ from that of forming (21) and involves the nucleophilic attack of aniline on the dimethyle acetylenedicarboxylate with formation of compound (21), through the following mechanism:
Compound (12) was further converted into their cyclic imide derivatives by treatment with different amines. The reaction of (12) with hydrazine hydrate at room temperature afforded the heterocyclic compound (13). The compound (13) was characterized by IR which showed a fundamental stretching band (doublet) due to NH2 at 3261 and 3209 cm-1. Compounds (14) and (15) prepared from reaction of (12) with urea and thiourea at room temperature, also showed a fundamental stretching bands (doublet) due to NH2 at 3250, 3200 and 3255 and 3205 cm-1 respectively. In general, IR spectra of the rest of the compounds (16-20) showed N-H stretching at about 3450 to 3210 cm-1. In addition to that, the compounds (13-20) also showed two carbonyl (C=O) stretching absorption band for imides compounds at around 1710 to 1610 cm-1 , methoxy (C-O-C) band absorption at around 1240 to 1225 and C-N absorption band at around 1080 to 1031 cm-1.
1H-NMR spectra of the compounds (12-20) showed characterization signals at around δ 2.3 to 2.85 for CHNH, signals for NH at around δ 2.6 to 3.3, signals at around δ 5.1 to 5.65 for CHCO, aromatic protons signals were appeared at about δ 7.0 to 8.1 ppm.
Regarding 13C-NMR spectra for the same compounds (12-20), signals at around δ 27.1 to 30.1 for CH group adjacent to carbonyl group, signals for CH adjacent to NH group at around δ 30.8 to 34.4, signals at around δ 30.1 to 34.8 for tertiary carbon adjacent to the other carbonyl group. Signals that due to aromatic carbon appeared at around δ 125 to 149, the ipso-carbon showed signals at around δ 143.7 to 150.4 and important signals were observed due to carbonyl group carbons at about δ 175.1 to 182.3 ppm. Microanalysis (CHN) of the compounds (12-20) confirms the molecular weight of the desired compounds.
