概要

• 論文の詳細を見る

• The reaction of olefins with bromomalonic ester and 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) proceeded in the presence of a catalytic amount of copper(II) halide to give 1,1-bis(alkoxycarbonyl)cyclopropane derivatives. DBU was converted into DBU-hydrobromide during the reaction. The reaction was electrophilic and proceeded nonstereospecifically.
