Stefani, Hélio A.,Costa, Iguatemi M.,De O. Silva, Diogo,Menezes, Paulo H.,Rodrigues, Alessandro
, p. 141 - 152 (2007/10/03)
Selenocyclofunctionalization of α-substituted β-ketoamides obtained from the aminolysis of the ethyl acetoacetate yielded dihydrofurans in moderate to good yields.
Ruthenium complex-catalyzed allylic alkylation of carbonucleophiles with allylic carbonates

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.
