Abstract: Electrochemical conversion of biomass-derived intermediate compounds to high-value products has emerged as a promising approach in the field of biorefinery. Biomass upgrading allows for the production of chemicals from non-fossil-based carbon sources and capitalization on electricity as a green energy input. Amino acids, as products of biomass upgrading, have received relatively little attention. Pharmaceutical and food industries will benefit from an alternative strategy for the production of amino acids that does not rely on inefficient fermentation processes. The use of renewable biomass resources as starting materials makes this proposed strategy more desirable. Herein, we report an electrochemical approach for the selective oxidation of biomass-derived α-hydroxyl acids to α-keto acids, followed by electrochemical reductive amination to yield amino acids as the final products. Such a strategy takes advantage of both reactions at the anode and cathode and produces amino acids under ambient conditions with high energy efficiency. A flow electrolyzer was also successfully employed for the conversion of α-hydroxyl acids to amino acids, highlighting its great potential for large-scale application.

INTERMEDIATE: (5-Methoxy-3-methyl-quinoxalin-2-yl)-hydrazine (lie). 2-Methoxy-6-nitro- phenylamine (25.0 g) was dissolved in 37% aq HC1, and the mixture ws cooled on an ice/water bath. A solution of NaN02 (11.8 g) in water (3 mL) was added, and the resulting mixture was stirred at 0 C for 15 min. The reaction mixture was added to a solution of cuprous monochloride (14.7 g) in 37% aq HC1 (10 mL) under stirring at 45-50 C. The resulting mixture was stirred at 50 C for 15 min, cooled at 5 C for 15 min. The solid was filtered off and dried to give 2-chloro-l-methoxy-3- nitrobenzene (16.5 g). A mixture of 16 g of this material, racemic alanine (17 g), and K2CO3 (12 g) was heated in DMSO (180 mL) at 100 C for 24h. The volatiles were removed using a freeze dryer. The residue was acidified with 2M aq HC1 (50 mL) and extracted into EtOAc. The organic extract was extracted with 2M aq Na2C03 and water. The combined aq extracts were acidified with 2M aq HC1 and extracted with EtOAc. The organic layer was washed with brine, dried over MgSO i, filtered, and concentrated in vacuo to afford 2-(2-methoxy-6-nitro-phenylamino)-propionic acid. This material was dissolved in ethanol (600 mL) and 96%> sulphuric acid (6 mL) was added. The mixture was heated at 80 C overnight. The volatiles were removed in vacuo and the residue was dissolved in EtOAc and washed with 2M aq Na2C03. The organic layer was dried over MgSO i, filtered, and concentrated in vacuo to afford 2-(2-methoxy-6-nitro-phenylamino)-propionic acid ethyl ester (8.0 g). This material was dissolved in ethanol (300 mL) and 5% palladium on carbon was added. The mixture was treated with 3 bars of hydrogen pressure on a Parr shaker for 3h. The catalyst was filtered off, and the filtrate was concentrated in vacuo. The residue was purified by chromatography on silica (eluent: heptanes? EtOAc) to afford 5-methoxy-3-methyl-3,4-dihydro- lH-quinoxalin-2-one (3.0 g). This material was dissolved in ethanol (300 mL) and treated with 30% aq hydrogen peroxide at 80 C overnight. Most of the volatiles were removed in vacuo. The residue was suspended in ethanol (10 mL) and cooled on an ice/water bath before the solid was filtered off, washed with ice-cold ethanol, and dried to afford 5-methoxy-3-methyl-lH-quinoxalin-2-one (2.2 g). This material was dissolved in phosphoryl chloride (24 mL) and heated at 130 C for 2h. The volatiles were removed in vacuo. The residue was partitioned between chloroform and ice + 2M aq NaOH. The organic layer was dried over MgSO i, filtered, and concentrated in vacuo to afford 2- chloro-5-methoxy-3-methyl-quinoxaline (2.5 g). This material was dissolved in ethanol (22 mL), hydrazine hydrate (2.9 mL) was added, and the mixture was refluxed for 2h. The volatiles were removed in vacuo, and water was added. The solid was filtered off, washed with water and heptanes and dried to afford lie (1.70 g) sufficiently pure for the next step.

In two selectedcases [FeCl2 and Fe2(SO4)3·9H2O], NH2CHO (200 muL) wasmixed with the sodium silicate solution (2.0 mL) in the presence of selected growing MSH (starting from 2.0% w/w ofthe corresponding salt?s pellet) at 80 C for 24 h. For the innerenvironment, NH2CHO (200 muL) was mixed with distilledwater (2.0 mL) in the presence of selected MSH (2.0% w/w) at80 C for 24 h. The reaction of NH2CHO (10% v/v) with thesodium silicate solution (pH 12) without MSH membranes wasalso analyzed under similar experimental conditions. Theproducts were analyzed by gas chromatography associatedwith mass spectrometry (GC-MS) after treatment with N,Nbis-trimethylsilyl trifluoroacetamide in pyridine (620 muL) at 60C for 4 h in the presence of betulinol (CAS Registry Number473-98-3) as the internal standard (0.2 mg). Mass spectrometrywas performed by the following program: injection temperature280 C, detector temperature 280 C, gradient 100 C for 2min, and 10 C/min for 60 min. To identify the structure of theproducts, two strategies were followed. First, the spectra werecompared with commercially available electron mass spectrumlibraries such as NIST (Fison, Manchester, U.K.). Second, GCMSanalysis was repeated with standard compounds. Allproducts have been recognized with a similarity index (SI)greater than 98% compared to that of the reference standards.The analysis was limited to products of ?1 ng/mL, and theyield was calculated as micrograms of product per startingformamide.
