摘 要:以二氯乙腈為起始原料,與蘇氨酸甲酯在甲醇鈉催化下形成噁唑啉中間體,經(jīng)過(guò)消除、酸催化得到含有噁唑環(huán)的氯化物,碘化鉀取代后與三苯基磷形成Wittg鹽,后者與丁特基二甲基氯硅烷(TBS)保護的香蘭素進(jìn)行Wittig反應,得到只有潛在抗病毒活性的天然產(chǎn)物Siphonazole中的重要片段,總收率為44%。 |
關(guān)鍵詞:Siphonazole;鹵代噁唑;Wittig反應 |

Abstract:Oxazoline intermediate was synthesized from dichloroacetonitrile in the presence of the catalyst sodium methanol, and further give oxazole chloride via elimination and acidic catalyzation. Oxazole chloride was substituted by potassium iodine, and then reacted with triphenyl phosphorus to give the Wittig salt, and reacted with vanillin with tert-butyl dimethylchlorosilane through Wittig reaction to get the natural products siphonazole with potential antiviral activity .Overall yield of siphonazole was 44%. |
Key words:Siphonazole;halogenated oxazole;Wittig reactions |
