YieldReaction ConditionsOperation in experiment
12.9 g (65%) 3 Example 3 Example 3 21 g (179 mmol) of gamma-vinylbutyrolactone prepared as in Example 1 were stirred with 100 ml of 25% strength aqueous ammonia in an autoclave at 270° C. for two hours. After cooling, the reaction mixture was concentrated at 50° C./20 mbar. The residue (19 g) was distilled using a spinning band column to yield 12.9 g (65%) of 5-vinylpyrrolidone, boiling point 88°-95° C./0.3 mbar.

YieldReaction ConditionsOperation in experiment
96% With 1,2-Bis(phenylsulfinyl)ethane; palladium diacetate; p-benzoquinone In ethyl acetate at 20℃; for 96h; Molecular sieve;
59% With 1,2-Bis(phenylsulfinyl)ethane; sodium acetate; palladium diacetate; 2-phenyl-1,4-benzoquinone In dichloromethane at 45℃; for 24h; Sealed tube; Inert atmosphere; Synthesis and Characterization of vinyl-lactones 2b-d General procedure: In a sealed tube, under an argon atmosphere, were added the carboxylic acid (1.0 equiv.), Pd(OAc)2 (0.1equiv.), bis-sulfoxide ligand (0.15 equiv.), p-phenylbenzoquinone (1.07 equiv.), NaOAc (1.0 equiv.) and CH2Cl2(0.5 M). The tube was stoppered and the reaction was allowed to stir at 45 °C. After 24 h, the reaction mixturewas filtered on a plug of Celite. The filtrate was treated with a saturated aqueous solution of 5% K2CO3 andthe aqueous layer was extracted with CH2Cl2 (3x). The combined organic layers were dried over anhydrousMgSO4, filtered and concentrated under reduced pressure. Purification by flash silica gel columnchromatography afforded the desired vinyl-lactone
