An efficient asymmetric totalsynthesis of cryptorigidifoliol I based on an unusual Luche reduction leading to bicyclic etherification and acid hydrolysis to a thermodynamically less stable 4-hydroxy-2,6-trans-disubstituted-THP moiety has been achieved. The easy setup of trans-2,6-substitution on the core pyran ring through bicyclic etherification would enable the synthesis of various THP and bicyclic-THP-lactone
基于不寻常的 Luche 还原,导致双环醚化和酸水解成热力学不稳定的 4-羟基-2,6-反式-二取代-THP 部分,已经实现了 Cryptorigidifoliol I 的有效不对称全合成。通过双环醚化在核心吡喃环上轻松设置反式-2,6-取代基,可以合成各种THP和双环-THP-内酯天然产物。
