摘要:
An efficient method for the enantioselective synthesis of beta-tertiary beta-amino alcohol derivatives through Pd-catalyzed decarboxylative cycloaddition of vinylethylene carbonates with imines was developed. By using a palladium complex generated in situ from [Pd-2(dba)(3)]center dot CHCl3 and phosphoramidite L2 as a catalyst under mild reaction conditions, the process provided 4-substituted-4-vinyloxazolidines in good to high yields with high levels of enantio- and diastereoselectivities.
