摘要

A series of terpene α-chlorohydrins was synthesized in 44–89% yields by the reduction of the corresponding α-chloro ketones using NaBH4. In turn, α-chloro ketones were synthesized from the secondary terpene alcohols by a one-pot procedure using the ClO2—DMF oxidative-chlorinating system. α-Chloro ketones demonstrated significantly higher antifungal activity than the corresponding chlorohydrins and oxygen-containing terpenoids and in some cases their activity is comparable to or exceed the activity of the antifungal reference drugs fluconazole and ketoconazole.
