Treatment of the olefinic epoxy alcohol 4 with diethylaluminum fluoride gives the hydroxymethyl methylenecyclohexanol 5 in yields of 60–75% rather than the other possible epoxide opening product 6 presumably due to a geometrical constraint similar to that in Baldwin's rules for ring closure.
用氟化二乙基铝处理烯烃环氧醇4可以得到60-75%的羟甲基亚甲基环己醇5,而不是其他可能的环氧开环产物6,这可能是由于其几何约束类似于鲍德温的闭环规则所致。
