The stereocontrolled synthesis of goniothalesdiol A, a dihydroxylated tetrahydropyran compound, has been accomplished using D‐ribose as chiral precursor. The key steps involved are aryl Grignard reaction, stereoselective alkoxy‐directed keto reduction, and intramolecular oxy‐Michael addition.
使用D-核糖作为手性前体,可以完成立体式合成鼠李素A(一种二羟基化的四氢吡喃化合物)的立体控制。涉及的关键步骤是芳基格氏反应,立体选择性烷氧基指导的酮还原以及分子内氧迈克尔的加成。
