The Baeyer-Villiger reaction of bicyclo[3.1.1]heptanones yields the expected lactones, but with some difficulty. These lactones readily react with alcohols, including the ethanol present in commercial chloroform, to give the corresponding hydroxy esters. Pinocamphone and isopinocamphone exhibit conformational control in the Baeyer-Villiger reaction, the trans-isomer yielding mainly the expected lactone
双环[3.1.1]庚酮的Baeyer-Villiger反应可产生预期的内酯,但存在一定难度。这些内酯容易与醇(包括存在于商业氯仿中的乙醇)反应,生成相应的羟基酯。Pinocamphone和isopinocamphone在Baeyer-Villiger反应中显示构象控制,反式异构体主要产生预期的内酯,顺式异构体(isopinocamphone)生成羟氧异opinocamphone。讨论了将该途径用作合成环丁烷单萜的途径。
