The title 1-butenols 5b and 6b were obtained by isomerization of 2-butenols 2b and 3b catalyzed by potassium tert-butoxide ( tBuOK) in dimethylformamide ( DMF). Reaction of Z-olefin 2b was highly stereoselective to give E-isomer 5b whereas E-olefin 3b afforded predominantly Z-isomer 6b. Compounds 5b and 6b are substrates for adenosine deaminase, 6b being substantially less active than 5b.
通过
叔丁醇钾(tBuOK)在二甲基甲酰胺(
DMF)中催化
2-丁烯醇2b和3b的异构化,获得标题1-
丁烯醇5b和6b。Z-烯烃2b的反应是高度立体选择性的,得到E-异构体5b,而E-烯烃3b主要得到Z-异构体6b。化合物5b和6b是
腺苷脱氨酶的底物,6b的活性明显低于5b。
