报道了一种适当保护的(1R,2S,4S,5S)-4-amino-1-(hydroxymethyl)bicyclo[3.1.0]hexan-2-ol,的对映选择性合成方法,它是合成构象锁定碳环核苷的关键原料,包括抗病毒活性的北甲基卡巴胸苷。以2-脱氧核糖为起始原料,以33%的总收率合成了目标的Boc保护胺,其反应条件比以往的方法更环保。
An enantioselective synthesis of suitably protected (1R,2S,4S,5S)-4-amino-1-(hydroxymethyl)bicyclo[3.1.0]hexan-2-ol, a key starting material for the synthesis of conformationally locked carbocyclic nucleosides, including the antiviral active North-methanocarba thymidine, is reported. Starting from 2-deoxyribose the target Boc-protected amine was prepared in 33% overall yield under condition that are ecologically friendlier than previous methods.
