Abstract

Abstract A trimeric lignin model compound composed of α-O-4 and β-O-4 linkages was prepared by the microwave-assisted synthesis, which consisted of three steps:(a) the synthesis of 3-methoxy-4-benzyloxyacetophenone (2) from acetovanillone (1),(b) the bromination of compound 2 to produce 3-methoxy-4-benzyloxy-α-bromoacetophenone (3), and (c) followed by a nucleophilic substitution of compound (3) to obtain 3-methoxy-4- ...
