    'Staff publications' is the digital repository of Wageningen University & Research

    'Staff publications' contains references to publications authored by Wageningen University staff from 1976 onward.

    Publications authored by the staff of the Research Institutes are available from 1995 onwards.

    Full text documents are added when available. The database is updated daily and currently holds about 240,000 items, of which 72,000 in open access.

    We have a manual that explains all the features

Simple β-O-4’ linked dimeric model compounds are often targeted as substrate to mimic the reactivity of lignin in enzymatic or chemical treatments. These models mimic the structure and reactivity of regular β-O-4′ linkages in lignin, but are less suitable to predict the reactivity of acylated β-O-4′ substructures, which are abundant in various types of lignin. Here, we present a one-step lipase-catalyzed acylation of a commercially available lignin model compound with p-coumaric acid, p-hydroxybenzoic acid, cinnamic acid and acetic acid as acyl donors. This facile procedure allows to obtain new and relevant lignin model compounds at milligram scale, with simple purification of products and unreacted substrate.
