An efficient and stereocontrolled synthesis of 2-substituted tetrahydrofurans has been achieved. The approach employs the asymmetric reduction of γ-phenylseleno ketones obtained by three different procedures that are peculiarly applied to the synthesis of such compounds. Finally, the intramolecular substitution of the phenylselenone residue by the oxygen atom of a hydroxy group gives the tetrahydrofuran
已经实现了2-取代的四氢呋喃的有效和立体控制的合成。该方法采用了通过三种不同方法获得的γ-苯基硒代酮的不对称还原,这些方法特别适用于此类化合物的合成。最后,通过羟基的氧原子将苯硒酮残基进行分子内取代,得到四氢呋喃环。
