利用Mitsunobu反應合成芳基吡啶烷基醚

摘 要:在室溫下,以取代苯酚1a-b和吡啶烷基醇2a-d為原料通過(guò)Mitsunobu反應合成了相應的芳基吡啶烷基醚,反應收率為45% ̄70%,反應物2和1之比為1.11∶(摩爾比)。結果表明當酚的6-位取代基為甲氧基時(shí),產(chǎn)物的收率比6-位上沒(méi)有取代基時(shí)的收率高;溶劑對反應收率的影響不大。并用1H NMR、13C NMR和MS等對產(chǎn)物的結構進(jìn)行了測定。

Abstract:A few of aryl pyridylalkyl ethers were synthesized by Mitsunobu reaction from substituted phenols 1a-b and pyridyl alcohols 2a-e at room temperature in 45%~70% yields.The ratio of 2 to 1 is 1.1 ∶ 1(mol/mol).The yield of the reaction of 2-iodo-6-phenol was higher than those obtained with 2-iodo-phenol,and the solvent has little effect on the yield of the reaction.The structure of the products were assigned with 1H NMR?13C NMR and MS.
Key words:ether; Mitsunobu reaction; synthesis
