Selective Ether/Ester C–O Cleavage of an Acetylated Lignin Model via Tandem Catalysis
摘要:
Selective ether/ester C-O bond hydrogenolysis of an acetylated lignin model is achieved using a thermodynamically leveraged tandem catalytic strategy. Acetylation serves to (1) solubilize both lignin and lignin models and to (2) modify the reactivity of pendant hydroxy groups to promote more selective C-O cleavage.

The depolymerization of the biopolymer lignin can give pure aromatic monomers but selective catalytic approaches remain scarce. Here, an approach was rerouted to deliver an unusual phenolic monomer. This monomer's instability proved challenging, but a degradation study identified strategies to overcome this. Heterocycles and a useful synthetic intermediate were prepared. The range of aromatics available
