of a prochiral bis-hydroxymethyl group with the epimerization of a chiral furanyl ether in a single transformation, high levels of double diastereoselectivity have been achieved in a synthesis of 2,4,5-trisubstituted tetrahydropyrans, which proceeds under thermodynamic control.
在一次转化中,将前手性双羟甲基的去对称化与手性呋喃基醚的差向异构化相结合,在2,4,5-三取代的四氢吡喃的合成中实现了高水平的双非对映选择性,该合成在热力学控制下进行。
