concise synthetic route for obtaining noviose, the deoxy sugar component of aminocoumarin antibiotics. l-(+)-Noviose was successfully synthesized by utilizing a palladium-catalyzed epoxide-opening reaction and the subsequent lactone formation as key reactions, starting from a nonsugar chiral epoxide, which is easily available in both enantiomeric forms. noviose - novobiocin - aminocoumarin antibiotics - palladium-catalyzed
我们建立了一种新颖,简洁的合成路线,以获取新颖的,氨基香豆素抗生素的脱氧糖成分。通过利用钯催化的环氧化物开环反应和随后的内酯形成作为关键反应,成功地合成了1 -(+)-Noviose,该反应是从非糖手性环氧化物开始的,其容易以两种对映体形式获得。 新生-新霉素-氨基香豆素类抗生素-钯催化的环氧化物开口
