摘要
以(3R,4R)-3-[(1R)-叔丁基二甲基硅氧乙基]-乙酰氧基氮杂环丁-2-酮(4AA)为原料,经取代、酰化、Wittig反应,合成了标题化合物,化合物结构经1HNMRI、R、元素分析和质谱表征。
The compound ethyl ( 5 R, 6 S ) -2- ( 4-methoxyphenyl )- 6-[ ( 1R )-tert-butyldimethylsilyloxyethy ]-penem-3-carboxylate was synthesized from the starting material azetidinone via displacement, acylation and the Wittig reaction. The target product was characterized by ^1HNMR, IR, elementary analysis and MS.
