Facile Synthesis of α-Keto Acids and Esters by Palladium-Catalyzed Decarboxylation Reactions of Diallyl α-Oxalcarboxylates

Shimizu, Isao,Makuta, Toshiyuki,Oshima, Masato

, p. 1457 - 1460 (2007/10/02)

Reaction of diallyl α-oxalcarboxylates with formic acid in the presence of palladium catalyst gave α-keto acid in good yields.When the reaction was carried out without formic acid, decarboxylation-allylation took place to give allyl β-allyl-α-keto carboxylates.
