Synthesis of New Tripodal Hydroxybenzoic Esters and their Reaction with Tris-(2-aminoethyl)amine under High Pressure Conditions

The new simple method of synthesis of tripodal esters, building blocks for monomacrocyclic pendant macrocycles and bicyclic cryptands is reported. Six new tripodal esters, derivatives of hydroxybenzoic acids were prepared and characterized, and their reaction with tris(2-aminoethyl)amine carried under high pressure conditions was studied using Electrospray Ion Mass Spectrometry
