Palladium-Catalyzed Insertion of CO2 into Vinylaziridines: New Route to 5-Vinyloxazolidinones
摘要:
2-Vinylaziridines undergo a mild Pd-catalyzed ring-opening cyclization reaction with an ambient atmosphere of carbon dioxide to give 5-vinyloxazolidinones. The process is high yielding as well as regio- and stereoselective.

The palladium-catalysedcarbonylation of vinyl aziridines can give either the trans- or cis-beta-lactam preferentially or even the delta-lactam simply by adjusting the reaction parameters ([Pd], [CO], temperature).
