YieldReaction ConditionsOperation in experiment
With water;HUSY (Si/Al=15); at 250℃; under 5250.53 Torr; for 2h;Inert atmosphere;Product distribution / selectivity; In an autoclave (batch reactor) lignin (0.5 g), HUSY (Si/Al=15) (0.5 g) and mixture of water and organic solvent (30 g) were charged. After flushing the reactor with nitrogen gas for 3 times, nitrogen (7 bar) was charged. Reactor was heated up to 230° C. under the stirring (100 rpm). After attaining the desired temperature of 230° C. stirring was increased up to 500 rpm. Reaction was stopped after 30 minutes. Analysis of reaction mixture was done by GC, GC-MS. The lignin used in these examples were organosolv or dealkaline.Yield: >25percentMass balance: >90percent.The effect of reaction temperature and reaction time on depolymerization reaction is demonstrated by the results presented in Table 8 using SiO2-Al2O3 as catalyst*.

YieldReaction ConditionsOperation in experiment
12% With sodium hydroxide; In ethanol; water; at 0 - 20℃; General procedure: To a solution of each of substituted 4-phenylbut-3-en-2-ones(7a1-d1, 7e, 7f and 7c3) and substituted 3-phenylacrylaldehydes (8a1-d1, 8c3 and 8a2-b2) in ethanol was added 20% (w/v) aqueous NaOH at 0-5 C. The mixture was allowed to stir at ambient temperature until the starting material was consumed, during which time the progress of the reaction was monitored by TLC. Development of dark orange coloration indicated that the reaction has taken place. Ethanol was removed in vacuo; ice-water was added to the residue and the solution was neutralized with cold 3M HCl (or acidified to pH ca. 1-2 in the case of 4 and 5, the intermediates 3-phenylacrylaldehydes 8a2 and 8b2 were used, respectively). The solid was collected by vacuum filtration (or extracted with EtOAc and the solvent was evaporated to dryness), washed with water and dried. The residue was purified by column chromatography or recrystallized from appropriate solvent system to provide the substituted trienone analogues 4, 5, 9-15 and 17-20.

YieldReaction ConditionsOperation in experiment
22% With D-glucose; In aq. phosphate buffer; at 30℃; for 16h;pH 8.0;Enzymatic reaction; General procedure: Glucose (22.2 mM), E. coli BL21(DE3)/pETDuet-1-PPTase-CAR (wet cells, 10 g), and the substrate (20a, 5.0 mM) were mixed in the sodium phosphate buffer (100 mL, 100 mM, pH 8). The resulting mixture was incubated at 200 rpm in a rotary shaker at 30°C, and the reaction was monitored by GC. After 29 h, the pH of the reaction mixture was adjusted to 2?3 with 2 M HCl and the mixture was filtered through a Celite pad to remove the biomass. The resulting aqueous solution was extracted with ethyl acetate. The organic phase was dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure. The residue was puriedby a silica gel column to give the product.
