    • While authentic b-O-4 lignin models always have OH or OR trans to the benzylic carbon, work by Gold et al.[ 18] showed that the 3,5-dimethoxylated aryl ring model used here gave similar oxidation products. We employed a 13C-labeled version of 1a in previous work[16a] and wanted to compare our results here with the analogous substrate
