YieldReaction ConditionsOperation in experiment
87% With acetyl chloride; at 20℃; for 1h; To 3-benzoylpropionic acid (15 g, 0.084 mol), acetyl chloride (150 mL, 2.1 mol) was added and the mixture was stirred at room temperature for 1 h. The acetyl chloride excess was removed in vacuo. Recrystallization of the residue from diethyl ether afforded 5-phenylfuran-2(3H)-one, light yellow powder, m.p. 86-88 C (cf. Ref. 23: 88-89 C), yield 11.7 g (87%). 1H NMR (CDCl3), delta: 3.42 (d, 2 H, CH2, J = 2.3 Hz); 5.79 (m, 1 H, CH); 7.38-7.47 (m, 3 H, m-Ph, p-Ph); 7.58-7.63 (m, 2 H, o-Ph).
43% With acetic anhydride; at 90℃; for 5h; [0095] The compound 10 was synthesized in accordance with the following scheme. [C00004] [00004] [0096] Namely, 1.80 g (10.1 mmol) of 3-benzoylpropionic acid (11) was heated at 90 C. for 5 hours in 10 ml of acetic anhydride. After removing the solvent, the reaction mixture was purified by silica gel column chromatography (hexane:ethyl acetate=10:1) to obtain 705 mg (43%) of a lactone body 12.

YieldReaction ConditionsOperation in experiment
85% With triethylamine In dichloromethane at 20℃; for 18h; 4.2. General procedure for the synthesis of α,α-bisthiofunctionalized butenolides 3 General procedure: To a test tube equipped with a magnetic stirring bar were sequentially added butenolides 1 (0.20 mmol), N-(arylsulfanyl)succinimides 2 (0.41 mmol), and Et3N (0.02 mmol) in DCM (2.0 mL).Then the mixture was stired for indicated time at room temperature. After completion of the reaction, as monitored by TLC, the solvent was removed under reduced pressure, and the residue was subjected to flash chromatography on silica gel (petroleum ether/ethyl acetate 30/1) to give the corresponding product 3.

YieldReaction ConditionsOperation in experiment
98% With pepsin In water at 50℃; for 48h; Green chemistry; Enzymatic reaction; diastereoselective reaction; 4. General procedure for the pepsin-catalyzed vinylogous Michael addition General procedure: A round bottom flask was charged with γ-substituted butenolide (0.2 mmol), maleimide (0.4 mmol), pepsin (19.5 kU) and deionized water (1.0 mL). The resulting mixture was stirred at 50 °C and was monitored by TLC. Upon completion of the reaction, the enzyme was filtered out, and ethyl acetate was added to wash the filter cake and tomake the product dissolved in the filtrate. The organic layer was separated with a separatory funnel, and the solvent was removed under reduced pressure. The residue was purified by silica gel flash column chromatography with petroleum ether/ethyl acetate (2:1-1:1) as eluent to afford the product.
