摘要

Abstract The ruthenium-catalyzed one-pot double allylation/cycloisomerization of 1, 3- diketones and methyl acetoacetate gave exo-methylenecyclopentanes in moderate to good yields with high isomer selectivity. The double allylation step effectively proceeded in the presence of a Ru II precatalyst,[Cp* RuCl (cod)], in 1, 2-dichloroethane at 90 C. The subsequent cycloisomerization was carried out upon addition of triethylsilane as a hydride ...
