A stereoselective and high yielding route is described to a suitably protected derivative of (3S, 4R, 5S)-(+)-3-amino-4,5-dihydroxycyclopent-1-ene, the side chain moiety of queuosine. The synthetic route comprises a ring-closing metathesis (RCM) of a mannofuranose-derived diene followed by Overman rearrangement.
描述了对(3S,4R,5S)-(+)-3-氨基-4,5-二羟基环戊-1-烯,即奎松碱的侧链部分的适当保护的衍生物的立体选择性和高产率的途径。合成途径包括甘露呋喃糖衍生的二烯的闭环易位(RCM),然后进行超人重排。
