Reaktionsschritte
A 70 mL stainless steel high pressure reactor having a Pyrex glass liner and a magnetic stir bar was charged with 5 mL of tetrahydrofuran, 0.5 mmol of n-pentadecane internal standard, 0.5 mmol of C2H5OH, 40 mg of (PPh3)2PdCl2, and 55.5 mg of N-acetyl-2-pyrroline. The reactor was pressurized to 1000 psi with CO at room temperature, and the reaction mixture was stirred at 100° C. for 21 hours. Thereafter, the reactor was cooled to room temperature and vented to atmospheric pressure. The product mixture was analyzed by gas chromatography and mass spectrometry, and the analysis indicated 100% conversion of N-acetyl-2-pyrroline and 34% yield of N-acetylproline ethyl ester.
