A general and efficient route for the synthesis of 5,6-seco-hexahydrodibenzopyran and trans-hexahydrodibenzopyran analogues was established, via a highly regio- and stereoselective SN2′ reaction of arylcyanocuprates to enol silyl ether of α,β-epoxycyclohexanone. It was applied to the first facile total synthesis of (+)-Machaeridiol B and (+)-Machaeriol B.
通过芳基氰基丙酸酯对α,β-环氧环己酮的烯醇甲硅烷基醚的高度区域选择性和立体选择性S N 2'反应,建立了合成5,6-癸基-六氢二苯并吡喃和反式-六氢二苯并吡喃类似物的一般有效途径。将其应用于(+)-Machaeridiol B和(+)-Machaeriol B的第一个简便的全合成。
