Tailoring the Oxidative Chemistry of Hydroxycinnamyl Alcohols: New and Green Access Routes to Lignans and Lignin Functional Derivatives
The oxidative reactivity of coniferyl alcohol (CA), sinapyl alcohol (SA), and p-coumaryl alcohol (PCA), the main lignin precursors, was systematically investigated under enzymatic and non-enzymatic conditions in both solution and solid-state. For CA, aqueous oxidation promoted the formation of β-O-4 and β-5 dimers, whe...
