An efficient and straightforward stereoselective synthesis of (6S)-6-[(2R)-2-hydroxy-6-phenylhexyl]-5,6-dihydro-2H-pyran-2-one is described. The chiral centers were generated by Sharpless asymmetric epoxidation followed by regioselective epoxide ring opening with Red-Al to afford 1,3-diols, exclusively. All the reactions were very clean and the products were obtained in very good yields.
描述了 (6S)-6-[(2R)-2-羟基-6-苯基己基]-5,6-二氢-2H-吡喃-2-酮的有效且简单的立体选择性合成。手性中心是通过 Sharpless 不对称环氧化反应生成的,然后用 Red-Al 进行区域选择性环氧化物开环,专门提供 1,3-二醇。所有反应都非常干净并且以非常好的产率获得产物。
