A Convenient Modified Short Route for the Preparation of [32]ane-N₈Hydrochloride

Abstract

A convenient modified short-cut route for the preparation of a 32-membered octaazamacrocyclic molecule, 1,5,9,13,17,21,25,29-octaazacyclodotriacontane hydrochloride, [32]ane-N8·8HCl has been described. The proper tetramine has been contemplated to go this new pathway which propagates [32]-N8·8HCl more effectively.

A macrocyclic polyamine as an anion receptor in the capillary electrochromatographic separation of carbohydrates

“…The macrocyclic polyamine is a highly promising ligand, however, the synthesis is usually more difficult than it appears in print [3]. Recently, we proposed a convenient modified short route for the preparation of 32-membered macrocylic polyamine [36]. These compounds are expected to exhibit high affinity and good selectivity not only for neutral guest molecules but also for greater ionic radii of anionic guest molecules.…”

Recognition of silver nanoparticles surface‐adsorbed citrate anions by macrocyclic polyammonium cations: a spectrophotometric approach to study aggregation kinetics and evaluation of association constant

“…Their aqueous solutions show pH 2.0. Another large protonated macrocycle, [32]ane‐N 8 .8HCl, was prepared (Misra et al ., ) and considered for the study. To study the interaction of Ag‐NPs functionalized citrate anions with these MCPACs, a half‐diluted aqueous solution of the as‐prepared cit‐Ag‐NPs was treated with different concentrations of Tet‐A.4HCl, Tet‐B.4HCl, or 32‐MCPAC and recorded their UV–Vis spectra after 30 min of mixing.…”

“…The precipitate were filtered off, dried, and recrystallized from ethanol-water mixture to give colorless crystals. A 32-MCPAC was prepared following the reported method (Misra et al, 2005).…”

Bioconjugation of 32-macrocyclic polyammonium cations-functionalized gold nanoparticles with BSA

“…Purified water (18 MX cm) from a Milli-Q water purification system (Millipore, Bedford, MA, USA) was used to prepare all solutions. Macrocyclic polyammonium chloride, 32-MCPAC, was prepared following the reported method [25].…”
