Cu-OMS-2-catalyzed decarboxylation–acetoxylation of (3R,4R)-4-acid-3-[(R)-1-((t-butyl-dimethylsilyl)oxy)-ethyl]-1-methoxyphenyl-2-azetidinone with NaBrO3/NaOAc

(3R,4R)-4-Acetoxy-3-[(R)-1((t-butyldimethylsilyl)oxy)-ethyl]-1-methoxyphenyl-2-azetidinone (an important precursor for the synthesis of carbapenem antibiotics) was synthesized under mild and green conditions catalyzed by Cu-OMS-2. Normal to excellent isolated yields were obtained under given conditions.
(3R,4R)-4-乙酰氧基-3-[(R)-1((叔丁基二甲基硅)氧基)-乙基]-1-甲氧基苯基-2-氮杂环丁酮(合成碳青霉烯类抗生素的重要前体)在 Cu-OMS-2 催化下于温和绿色条件下合成。在给定的条件下,获得了正常到极好的分离产率。
