An efficient enantioselective synthesis of (+)-isofregenedol was achieved in 13 steps from commercially available cyclohexene oxide without the use of protecting groups. The tetrahydronaphthalenic core of isofregenedol was obtained via a gold(I)-catalyzed benzannulation recently developed in our laboratory.
从市售的环氧环己烷出发,无需使用保护基团,经13步反应实现了(+)-异弗瑞格多醇的高效对映选择性合成。异弗瑞格多醇的四氢萘核心是通过我们实验室最近开发的金(I)催化的苯并环化反应得到的。
