## Abstract

In this research work, dinaphthyl sulfide diester was prepared from the reaction of 1,1′-thiobis (2-hydroxy naphthalene) and methylchloroacetate. Its aza-macrocyclic derivative was synthesized from the reaction of dinaphthyl sulfide diester and diethylenetriamine. Lariats were prepared from the reaction of chloroamides (four derivatives) and initial macrocycle. Chloroamides were synthesized from the reaction of amines (aniline, benzylamine, 8-amino quinoline and 4-amino azobenzene) and chloroacetyl chloride. All the materials were identified by IR,1H NMR, 13C NMR, and mass spectroscopies, and elemental analysis.

## Body

## 1. Introduction

Since the initial publications on the synthesis of crown ethers and their metal salt complexation properties [1, 2], the influence of structural variation within such ligands has received increasing attention [3–12]. One such structural variation is the replacement of one ether oxygen with nitrogen to give an azacrown ether [13, 14] or sulfur group to obtain thiacrown ether [14, 15]. Another is the attachment of a functional side arm to the ligand framework to provide the potential for three-dimensional complexation of metal ions. Such armed crown ethers have been designated as lariat ethers [16–18]. If the side arm attachment site is a carbon atom of the macrocycle, the ligand is called a C-pivot lariat ether. If it is a nitrogen atom of azacrown ether, the ligand is identified as a N-pivot lariat ether.Efficient syntheses of N-pivot lariat ethers in which phenolic and hydroxyquinoline units are attached to an aza crown ether nitrogen by a methylene group have been developed using the Mannich reaction [19]. A lot of lariat aza-macrocycles were synthesized in which their side chain containing several functional groups such as ether [20], amide [21, 22], acid [23], nitrogen [24], and other functional groups that have an active rule in binding properties towards various kinds of guests.BINOL is an important building block in chemistry. A large number of BINOL derivatives have been explored, and important BINOL derivatives are BINOL crown ethers and macrocycles. The study of optically active BINOL compounds and the new derivatives of these compounds is an active route in organic synthesis in recent years [25–32]. According to the Figure 1, BINOL and dinaphthyl sulfides are derivatives. In the dinaphthyl sulfides structure, sulfur atom is a strong donor atom for complexation properties and as a result dinaphthyl sulfide has stronger donor atoms in comparison with BINOL. Several works were performed for the application of dinaphthyl sulfide derivatives (podands and aza crowns): the study of complex formation with silver atoms [33], complexation with Pb2+, Ni2+, and Hg2+ [34], Hg2+ [35], Pb2+ [36], Ag+ [37], Cu2+ [38]. Dinaphthyl sulfide aza crowns diffuse across the cell membranes and interfere with different living systems [39]. All of these research works show that the dinaphthyl sulfide receptors have a large number of applications in chemistry and related areas.Figure 1

## 2. Experimental

The reactions were carried out in an efficient hood. All the materials were purchased from Merck, Fluka, and Aldrich chemical companies. Methanol and dichloromethane were distilled and stored under Lind 4 Å molecular sieves. Compound1 was synthesized based on the reported procedure [33–38]. Two chloroamides (6 and 7) were reported previously [40–42]. The melting points (uncorrected) were measured with an Electrothermal Engineering Ltd. 9100 apparatus. Elemental analysis was performed by a CHN–O– Rapid Heraeus elemental analyzer. IR spectra were measured on a Perkin-Elmer model 543, the 1H NMR and 13C NMR spectra were obtained using Bruker Avance DPX 300 MHz and Bruker Avance DRX 500 MHz apparatus, and mass spectra were obtained with Shimadzu GC-MS-QP 1100 EX model.

## 3. Results and Discussion

The key step in this project is the synthesis of aza-macrocycle (3). Dinaphthol (1) was synthesized from the reaction of 2-naphthol and sulfur dichloride based on the reported procedure [40–42]. The corresponding diester (2) was synthesized according to the modified reported procedure from the reaction of 1 and methylchloroacetate in the presence of potassium carbonate and catalytic amounts of KI in CH3CN and DMF (10 : 1) solvent mixture at room temperature [43, 44]. Macrocycle (3) was synthesized from the reaction of diester (2) and diethylenetriamine in the presence of catalytic amounts of p-toluene sulfonic acid (p-TsOH) in methanol (Scheme 1) [43]. The proposed mechanism for the formation of macrocycle (3) is appeared in Figure 2.Scheme 1
Synthesis of initial macrocycle (3).Figure 2
Proposed mechanism for the formation of macrocycle (3).Chloroamide derivatives (4–7) were synthesized from the reaction of corresponding amine and chloroacetyl chloride in the presence of triethylamine as base and in dichloromethane as solvent (Scheme 2) [40–42, 45], the lariat azacrowns (8–11) were synthesized from the reaction of chloroamides (4–7) and macrocycle (3). This reaction was carried out via a modified procedure in the presence of sodium carbonate and catalytic amounts of sodium iodide in CH3CN/DMF (10 : 1) at room temperature (Scheme 3) [46–48].Scheme 2
Synthesis ofα-chloroamide derivatives.Scheme 3
Synthesis of lariats (8–11).According to the previous works [33–38] on the applications of dinaphthyl sulfide receptors in host-guest chemistry, these new receptors are important candidates for a large number of studies such as complexation with metal ions, biological systems, and the applications in the preparation of nanostructures [44].


## 4. Conclusions

To summarize, we prepared a dinaphthyl sulfide aza crown, and then new dinaphthyl sulfide aza lariats (8–11) were prepared from the reaction of aza crown and some prepared chloroamides. This lariat is important receptors with naphthalene, quinolone, and azo groups. Based on the reported applications, the new receptors with pendant arms are strong complexation abilities and are potential candidates for host-guest chemistry and related areas.
