One-Pot Synthesis of Diverse Anion-Binding Macrocycles

Abstract

A one-pot synthetic protocol to access a diverse library of diamide–diester macrocycles from the same starting materials is reported. The molecular symmetry can be readily tuned based on the reaction sequence, while the core structure can be varied using amino acids and aromatic building blocks. The first class of macrocycles with C₂ axes in their molecular plane were obtained in 24 h with 40–70% yield, while another class with C₂ axes perpendicular to the plane were synthesized in 18 h in 10–30% yield. The phenyl- and serine-derived macrocycles of the first class could bind acetate, chloride, and phosphate ions. These macrocycles can be functionalized with hydrophobic groups and potentially be used as ion transporters.

Key words

• 19 General Procedure for the Synthesis of Macrocycle 1 To a solution of the diacid, i.e., 6-dipicolinic acid (3a) or isophthalic acid (3b, 1.75 mmol, 1 equiv), the requisite amino alcohol, i.e., methyl-l-serinate (4a) or methyl-l-threoninate (4b, 3.50 mmol, 2 equiv), HBTU (4.03 mmol, 2.3 equiv) in DCM, DIEA (17.5 mmol, 10 equiv) was added. The reaction was allowed to stir for 12 h. Subsequently, the second batch of the diacid, namely 2,6-dipicolinic acid (3a) or isophthalic acid (3b, 1.75 mmol, 1 equiv), HBTU (4.03 mmol, 2.3 equiv), and DMAP (0.2mmol, 0.1 equiv) were added to the same pot. The reaction mixture was allowed to stir for additional 12 h. The solvent was removed in vacuo and ethyl acetate (50 mL) was added to the residue. The resulting solution was washed sequentially with water (50 mL), 1 mol% HCl solution (50 mL), and sat. NaHCO₃ solution (50 mL). The organic layer was collected, dried over anhydrous sodium sulfate, filtered, and concentrated in vacuo. Purification with flash column chromatography afforded the macrocycle.
