3-methoxy-1,3,3-triarylprop-1-yne 2 or 1,1,3-triarylprop-2-yn-1-ol 2-OH to give the corresponding functionalized methylenecyclobutene, cyclobutane, and cyclopropane derivatives in the presence of Lewis acid BF3.OEt2 under mild conditions. A plausible Meyer-Schuster rearrangement mechanism has been proposed.
芳基亚甲基环丙烷1可以与3-甲氧基-1,3,3-三芳基丙-1-炔2或1,1,3-三芳基丙-2-炔-1-醇2-OH反应得到相应的官能化的亚甲基环丁烯,环丁烷和在路易斯酸BF3.OEt2存在下,在温和条件下制备环丙烷衍生物。提出了一种可行的Meyer-Schuster重排机制。
