## Abstract Mandelic and lactic acids are converted to the 1,3‐dioxolan‐4‐ones by treatment with acetone dimethyl acetal. Deprotonation followed by treatment with an allyl acetate and a catalytic amount (1 mol %) of palladium catalyst afforded the allylated dioxolanones, which could be hydrolyzed t

✦ Synopsis
a-Isocyanocarboxylates underwent palladium-catalyzed allylation with allylic acetates, in which n-allylpalladium(II) intermediate was involved. The catalytic allylation of methyl a-isocyano(phenyl)acetate using an optically active ferrocenylphosphine ligand caused an asymmetric induction of up to 39% ee.

The generation of quatenary chiral centers through catalytic asymmetric alkylation of ketone enolates has been the subject of investigation in recent years. [1] The palladiumcatalyzed asymmetric allylic alkylation (AAA) of prochiral nucleophiles represents one such strategy for the creation of quate
