New tetraheterocyclic macrocycles containing triazole, pyrazole, pyridine, and/or furan subunits. Synthesis and cation-binding properties

1,2,4-Triazoles: Synthetic approaches and pharmacological importance. (Review)

“…Examples where hydrazines provide the triazole ring [52][53][54] A series of neat unsymmetrically substituted 3,5-diaryl-4-methyl-4H-1,2,4-triazoles 34 were next thermolyzed at 330°C for 30 min to investigate the regioselectivity as a function of the electronic conditions induced by the para-substituents in one of the phenyl rings. These results were also compared with those obtained upon alkylation of the corresponding unsymmetrical 3,5-diaryl-1H-1,2,4-triazoles 35 with MeI.…”

Advances in polymer precursors and bio‐based polymers synthesized from 5‐hydroxymethylfurfural

“…(8) has been utilized to prepare high‐performance epoxies . 2,5‐bis(chloromethyl)furan (9) was synthesized by reacting (5) with SOCl 2 and pyridine in CHCl 3 at −10 °C . Furthermore, (9) has been used to obtain 2,5‐bis(azidomethyl)furan (10) and 2,5‐bis(cyanomethyl)furan (19) .…”

Metallomicellar catalysis: Hydrolysis of p-nitrophenyl picolinate catalyzed by Cu(II) complexes of triazole-based ligands in cationic gemini surfactant micelles

“…N-Alkyl-3,5-bis(hydroxymethyl)-1,2,4-triazole (L 2 -L 4 ) were synthesized from L 1 and the corresponding alkyl halides (methyl iodide for L 2 [31], and decyl bromide and dodecyl bromide for L 3 and L 4 , respectively). 3,5-Bis(hydroxymethyl)-1,2,4-triazole (6.45 g, 50 mmol) was added to a solution of potassium hydroxide (2.86 g, 50 mmol) in methanol (150 mL).…”
