  The present invention relates to a method for preparing 2′-O-fucosyllactose, the intermediates obtainable by this method and the use of these intermediates. The preparation comprises the reaction of a protected fucose of the general formula (I) with a tri(C 1 -C 6 -alkyl)silyl iodide to give a protected 1-iodofucose followed by the reaction of the protected 1-iodofucose with a compound of the general formula (II), in the presence of at least one base and deprotecting the resulting coupling product to afford 2′-O-fucosyllactose. In this context, the variables are each defined as follows: R a and R b are the same or different and are —C(═O)—C 1 -C 6 -alkyl, or —C(═O)-phenyl, wherein said phenyl is unsubstituted or optionally has 1 to 5 substituents, or R a and R b together are a radical —(C═O)— or a substituted methylene radical —C(R d R e )—, R c is a radical R Si or is benzyl, wherein said benzyl is unsubstituted or optionally has 1, 2 or 3 substituents, R Si is a radical of the formula SiR f R g R h , where R f , R g and R h are the same or different and are C 1 -C 8 -alkyl for example, R 1 is a radical —C(═O)—R 11 or a radical SiR 12 R 13 R 14 R 2 are the same or different and are C 1 -C 8 -alkyl for example; R 3 are the same or different and are for example C 1 -C 8 -alkyl or both radicals R 3 together form a linear C 1 -C 4 -alkenyl, which is unsubstituted or has 1 to 6 methyl groups as substituents.

  本发明涉及一种制备2'-O-岩藻糖乳的方法，以及通过该方法可获得的中间体和这些中间体的用途。该制备包括将一般式（I）的保护岩藻糖与三（C1-C6-烷基）硅基碘反应，得到保护1-碘岩藻糖，然后将保护1-碘岩藻糖与一般式（II）的化合物在至少一种碱的存在下反应，并去保护所得的偶联产物以得到2'-O-岩藻糖。在这种情况下，变量的定义如下：Ra和Rb相同或不同，为—C(═O)—C1-C6-烷基，或—C(═O)-苯基，其中所述苯基未取代或可选地具有1至5个取代基，或者Ra和Rb一起是一个基团—(C═O)—或一个取代亚甲基基团—C(RdRe)—，Rc是基团RSi或苄基，其中所述苄基未取代或可选地具有1、2或3个取代基，RSi是具有式SiRfRgRh的基团，其中Rf、Rg和Rh相同或不同，为C1-C8-烷基，例如，R1是基团—C(═O)—R11或基团SiR12R13R14，R2相同或不同，为C1-C8-烷基，例如，R3相同或不同，例如为C1-C8-烷基，或两个基团R3一起形成未取代或具有1至6个甲基基团作为取代基的线性C1-C4-烯基。
