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,经酰基取代、酰化、Wittig反应,合成了新化合物(5R,6S)-2-苯乙烯基-6-[(1R)-叔丁基二甲基硅氧乙基]-青霉烯-3-羧酸对硝基苄酯(6)。中间体和产物经1HNMR、IR、质谱表征。 A new compound ( 5 R, 6S ) -2-phenylethylene-6- [ ( 1 R) -tert-butyldimethylsilyloxyeth-yl ] -penem-3- carboxylic acid p-nitrobenzyl ester (6)was synthesized from the starting material optical azetidinone via acetyl displacement, acylation and Wittig reaction. The intermediates and the product were characterized by 1H-NMR, IR, and MS.
