Enzyme‐catalyzed CO2 fixation linked to chemical derivatization of the carboxylate product. (a) A strategy applying quaternary ammonium salt to shift the reaction equilibrium towards 1,6‐DHBD_Rs‐catalyzed carboxylation of resorcinol. The carboxylation step is linked to the precipitation of the carboxylate in one pot. The product was recovered by acid hydrolysis. 1,6‐DHBD_Rs=1,6‐dihydroxybenzoic acid decarboxylase. [100] (b) Pyruvate:ferredoxin oxidoreductase (PFOR)‐catalyzed CO2 fixation linked with derivatization using semicarbazide. [107]
