Abstract：

A　simple　two-step/one-pot　and　highly　efficient　strategy　for　the　synthesis　of　negletein　from　naturally　abundant　and　inexpensive　baicalin　has　been　developed.　In　this　one-pot　sequence,　esterification　of　baicalin　catalyzed　by　concentrated　H2SO4　in　methanol　followed　by　the　treatment　with　excess　NaBH4　afforded　negletein　in　moderate　yield.　This　method　provides　an　additional　approach　for　the　synthesis　of　negletein.　©　2016　Elsevier　Ltd.　All　rights　reserved.
