  摘要：

  1,2-双(嘌呤-6-基)乙炔，-二炔，-乙烯和-乙烷作为共价碱对类似物从6-乙炔基嘌呤和6-碘嘌呤出发，通过Sonogashira交叉偶联或氧化炔基二聚反应制备，随后进行氢化反应。类似地制备了6-[(1,3-二甲基尿嘧啶-5-基)乙炔基]嘌呤（11），并将其氢化为相应的嘌呤-嘧啶共轭物，通过乙烯和乙烷连接器连接。与细胞静止作用的双(嘌呤-6-基)乙炔和-二炔不同，嘌呤-嘧啶共轭物无活性。通过单晶X射线衍射测定了双(嘌呤-6-基)乙炔6a，-二炔8a和-乙烷5a的晶体结构。

  Purines bearing diverse β-substituted ethyl or vinyl groups in position 6 were prepared by the conjugate addition of N-, O- and S-nucleophiles to 6-vinylpurines or 6-ethynylpurines. The scope of this methodology was systematically studied. The addition of amines, alcoholates and thiolates to 6-vinylpurines gave the corresponsing 6-(2-aminoethyl)-, 6-(2-alkoxyethyl)- and 6-[2-(alkylsulfanyl)ethyl]purines

  The title bis(purin-6-yl)acetylenes, -diacetylenes, -ethylenes and -ethanes were prepared as covalent base-pair analogues starting from 6-ethynylpurines and 6-iodopurines by cross-coupling and homo-coupling reactions and hydrogenations. The bis(purin-6-yl)acetylenes and -diacetylenes exhibited significant cytostatic activity in vitro (IC(50)=0.4-1.0 micromol/l).

  Cyclotrimerization reactions of the 9-protected 6-ethynylpurines 4a,b in the presence of various transition metal catalysts were studied. The best results were obtained with Ni(COD)2 or Ni(COD)2/PPh3 to obtain the 1,2,4- and 1,3,5-tris(purin-6-yl)benzenes 5a,b and 6a,b in moderate to good yields (in a 4:1 to 10:1 ratio). This method is suitable for the practical synthesis of the unsymmetrical 1,2,

  A novel approach to 6-arylpurines based on [2+2+2]-co-cyclotrimerization of 6-alkynylpurines with various alpha,omega-diynes is described. Co-cyclotrimerization is catalyzed by Ni- and Co-phosphine catalysts and their choice depends on the substitution pattern of the both reactants. (C) 2003 Elsevier Science Ltd. All rights reserved.

  Transition metal complex catalyzed cocyclotrimerization of 6-alkynylpurines 1 with various diynes enables the preparation of a plethora of substituted 6-arylpurines 3 in good yields. The most general catalyst for the reaction is a user-friendly system based on a nickel-phosphine complex and reductant (NiBr2(dppe)/Zn) in MeCN. The reaction conditions are compatible with various protective groups on the purine moiety (Bn, THP). As far as other potential catalysts were concerned, only CoBr(PPh3)(3) showed reasonable activity in cocyclotrimerization of alkynylpurines with dipropargyl ether. A comparison of catalytic with stoichiometric approaches and the ligand effect in the catalyst is also given. Cytostatic activity screening of title 6-arylpurines was performed and several moderately active compounds were found.
