研究了α-芳基-α-重氮乙酸乙酯与氧取代乙烯的环丙化反应。α-芳基-α-重氮乙酸乙酯与三甲基硅基乙烯醚或乙基乙烯醚反应生成二氢呋喃，而醋酸乙烯酯则生成稳定的环丙烷，即2-乙酰氧基-1-芳基环丙烷羧酸乙酯，根据芳基取代基的性质和位置，分离收率为16-87%。
A study of cyclopropanations of oxy-substituted ethenes with ethyl α-aroyl-α-diazoacetates is described. The reaction of ethyl α-aroyl-α-diazoacetates with trimethylsilyl vinyl ether or ethyl vinyl ether gave dihydrofuran products, but when vinyl acetate was used the products were stable cyclopropanes, ethyl 2-acetoxy-1-aroylcyclopropanecarboxylates, which were isolated in 16–87% yield depending on the nature and position of the aryl-ring substituent.
