title: Palladium(II)-catalyzed tandem reaction of intramolecular aminopalladation of allenyl N-tosylcarbamates and conjugate addition.
abstract: A divalent palladium-catalyzed tandem cyclization-coupling reaction of allenyl N-tosylcarbamates and acrolein was developed. The reaction gave aldehyde-functionalized 2-oxazolidinones in one step with high regioselectivity. A mechanism involving intramolecular aminopalladation of allene, followed by insertion of alkene and C-Pd bond protonolysis, is proposed. [reaction: see text]
