    摘要:
    提出了一种催化锡自由基介导的自由基级联反应的一般策略,其中在一步中构建了三个环。三环化过程的初始步骤是使用在1-O和/或4-O位具有不饱和取代基的2,3-脱氧-α-D-赤藓糖亨糖醛进行研究。用于1-O位取代基环化的底物是通过一种新型的氯化锌催化的Ferrier重排反应,将三-O-乙酰化的D-葡糖醛与不饱和醇反应而制备的,而用于4-O位取代基环化的底物则是通过烷基化或酰基化反应,对乙基6-O-保护的2,3-脱氧-α-D-赤藓糖亨糖醛进行处理。丙炔基取代基能有效环化,但丙烯基取代基则较差。丙炔酰基取代基在没有环化的情况下经历了氢锡化反应。

  • Amine-linked diglycosides: Synthesis facilitated by the enhanced reactivity of allylic electrophiles, and glycosidase inhibition assays
    作者:Ian Cumpstey、Jens Frigell、Elias Pershagen、Tashfeen Akhtar、Elena Moreno-Clavijo、Inmaculada Robina、Dominic S Alonzi、Terry D Butters
    DOI:10.3762/bjoc.7.128

    Diglycose derivatives, consisting of two monosaccharides linked at non-anomeric positions by a bridging nitrogen atom, have been synthesised. Conversion of one of the precursor monosaccharide coupling components into an unsaturated derivative enhances its electrophilicity at the allylic position, facilitating coupling reactions. Mitsunobu coupling between nosylamides and 2,3-unsaturated-4-alcohols gave the 4-amino-pseudodisaccharides with inversion of configuration as single regio- and diastereoisomers. A palladium-catalysed coupling between an amine and a 2,3-unsaturated 4-trichloroacetimidate gave a 2-amino-pseudodisaccharide as the major product, along with other minor products. Derivatisation of the C=C double bond in pseudodisaccharides allowed the formation of Man(N4–6)Glc and Man(N4–6)Man diglycosides. The amine-linked diglycosides were found to show weak glycosidase inhibitory activity.

    由两个单糖通过桥接氮原子在非异头位置连接而成的双糖衍生物已经合成出来。将其中一个前体单糖耦合组分转化为不饱和衍生物,增强了其在烯丙基位置的亲电性,从而促进了耦合反应。nosyl酰胺和2,3-不饱和-4-醇之间的Mitsunobu耦合得到了反转构型的4-氨基-假双糖,作为单一的区位和对映异构体。胺和2,3-不饱和的4-三氯乙酰亚胺之间的钯催化耦合得到了2-氨基-假双糖作为主要产物,同时还得到了其他次要产物。在假双糖中对C=C双键的衍生化允许形成Man(N4–6)Glc和Man(N4–6)Man双糖苷。发现胺连接的双糖苷显示出较弱的糖苷酶抑制活性。
