Cyclohexanetricarboxylic acid

Problem 16.74 What compounds are formed on heating (a) 1,1,2-cyclohexanetricarboxylic acid, and (f>) 1,1,2-cyclobutanetricarboxylic acid ... 

Hydrogen-bonding motifs have also been observed with verdazyl radical-substituted pyridines, which co-crystallize with hydroquinone <2001JA7154>, and with iV-oxide derivatives of pyridine, such as found in co-crystals of 4,4 -bipyridine-iV-oxide and cyclohexanetricarboxylic acid <2005CE0551, 2005CGD1683>, bipyridine-iV-oxides with amino and nitrobenzoic acids <2005CGD727>, and bipyridine-iV-oxides and diphenols <2005CGD1041>. 

A receptor for cw-l,3,5-cyclohexanetricarboxylic acid has been reported by Ballester et al. (Figure 73) [99]. Evidence for three pairs of hydrogen bonds betwen the host and the guest was reported. An association constant greater than 10 was estimated. 

Scheme 6.3 Deterministic synthesis of cholesteric GLCs starting with monohydrolysis of a 1,3,5-cyclohexanetricarboxylic acid trimethyl ester with pig liver enzyme, PLE and b 1,3,5-benzenetricarboxylic acid trimethyl ester...

A highly interesting group of biocompatible hydrogelators was designed by Feringa and van Esch [70,71]. The approach is based on the 1,3,5-cyclohexanetricarboxylic acid scaffold onto which various lipophilic amino acid units were attached to give 1,3,5-triamide cis,cis-cyclohexane derivatives (Scheme 17).
