The ylides generated from carbenes (:CH2, :CHCO2Et, :CHPh) and oxetane in the presence of methanol undergo Stevens rearrangement and protonation competitively, yielding tetrahydrofurans and 1,3-dialkoxycyclopropanes as major products.
由甲醇(:CH 2,:CHCO 2 Et,:CHPh)和氧杂环丁烷在甲醇的存在下生成的酰化物竞争性地经历了史蒂文斯重排和质子化,产生了四氢呋喃和1,3-二烷氧基环丙烷为主要产物。
