Cinnamic acid polymerization
WebClassically, CGAs are a family of esters formed between quinic acid and certain trans -cinnamic acids, most commonly caffeic, p- coumaric, and ferulic acid. Representative structures are shown in Fig. 1 [2–4]. In the IUPAC system, (−)-quinic acid is defined as 1L-1 (OH),3,4/5-tetrahydroxycyclohexane carboxylic acid, but Eliel and Ramirez ...
