Article abstract of DOI:10.1246/cl.1995.525

Regioselective allylation of 2,4- and 4,4-diethoxycyclobuteones was performed with allylsilanes in the presence of BF3*Et2O via a common ethoxycarbenium ion intermediate.A merit of this reaction was demonstrated in an efficient conversion of the obtained
