| Download PDF Full-text (254 KB) | Abstract: Herein, we synthesized 2,3-diaminophenazine (DAP) from o-phenylenediamine (OP) using fungal laccase as a biocatalyst. The conversion ratio of OP monomer was 85% and the yield of the final purified product, DAP, was 63%. The structure of the main product, DAP, was confirmed by using several spectroscopy techniques (UV-VIS, IR, 2D-NMR, and MS).
