Palladium-catalysed decarboxylative carbonylation of 3-tosyl-5-vinyloxazolidin-2-ones 5 occurs at atmospheric pressure to give 1-tosyl-3,6-dihydro-1H-pyridin-2-ones 6. The reaction proceeds with no loss of enantiopurity and detosylation with sodium naphthalenide gives the title compounds in good yields.
