Allylic carbonates except for allyl methyl carbonate reacted with carbonucleophiles such as ethyl acetoacetate in the presence of a catalytic amount of Ru(cod)(cot) in N-methylpiperidine at 80 deg C to give the corresponding monoallylated carbonucleophiles in high yields with high regioselectivity.The regioselectivity was quite different from that in the palladium-catalyzed reactions.The allylation of carbonucleophiles using allyl methyl carbonate selectively gave the diallylated carbonucleophiles in high yields.
