Abstract: The research status of lignin model compounds synthesis was comprehensively summarized. Three main pathways of lignin monomer synthesis were introduced, including shikimic acid pathway, phenylpropane metabolizing pathway, and ester reduction pathway. The two theories of lignin monomer polymerization were sketched, i.e., the random polymerization theory(or free radical combinatorial coupling theory) which was widely accepted by academia and the controversial strict regulation polymerization theory. The research development of the chemical synthesis methods and mechanism of dimer, trimer and polymer from lignin model compounds bounded by β-O-4, α-O-4, 5-5', and β-5' bonds was illustrated. Meanwhile, some problems and countermeasures during the lignin chemical synthesis process were pointed out and the development direction of lignin model compounds synthesis research was confirmed.
