  Efficient palladium-mediated or base-induced 5-endo-dig cyclisation of C5-alkynylated pyrimidine derivatives: conventional and microwave-assisted synthesis of novel furo[2,3-d]pyrimidines

  摘要：

  A series of the novel 5-alkynyl- and furo[2,3-d]pyrimidine derivatives in which the sugar moiety is replaced by a methoxymethyl (MOM) group is synthesised using the Sonogashira cross-coupling reaction under both conventional and microwave conditions, in good to excellent yields. The 5-endo-dig cyclisation of 5-alkynylpyrimidine derivatives promoted by a Pd-catalyst or base gives the corresponding furo[2,3-d]pyrimidines in good yields. (C) 2012 Elsevier Ltd.

  Inhibition of Mycobacterial Replication by Pyrimidines Possessing Various C-5 Functionalities and Related 2′-Deoxynucleoside Analogues Using in Vitro and in Vivo Models

  摘要：

  Tuberculosis (TB) has become an increasing problem since the emergence of human immunodeficiency virus and increasing appearance of drug-resistant strains. There is an urgent need to advance our knowledge and discover a new class of agents that are distinct than current therapies. Antimycobacterial activities of several 5-alkyl, 5-alkynyl, furanopyrimiclines and related 2'-deoxynucleosides were investigated against Mycobacterium tuberculosis. Compounds with 5-arylalkynyl substituents (23-26,33, 35) displayed potent in vitro antitubercular activity against Mycobacterium bovis and Mycobacterium tuberculosis. The in vivo activity of 5-(2-pyridylethyny1)-uracil (26) and its 2'-deoxycytidine analogue, 5-(2-pyridylethynyI)-2'-deoxycytidine (35), was assessed in BA LB/c mice infected with M. tuberculosis (H 37 Ra). Both compounds 26 and 35 given at a dose of 50 mg/kg for 5 weeks showed promising in vivo efficacy in a mouse model, with the 2'-deoxycytidine derivative being more effective than the uracil analogue and a reference drug o-cycloserine. These data indicated that there is a significant potential in this class of compounds.

  Sonogashira coupling of 5-iodouracil (2) and trimethylsilylacetylene gave 5-(trimethylsilylethynyl)uracil (3), which was deprotected to give 5-ethynyluracil (4). Copper(I)-catalyzed cyclization of 4 gave furo[2,3-d]pyrimidin-2(3H)-one (5). Tosylation of 2 and 4 gave the 1-(p-toluenesulfonyl) derivatives 6 and 7, respectively. The tosylated compound 6 and trimethylsilylacetylene did not undergo Sonogashira coupling, and copper(I)-catalyzed cyclization of 7 did not occur. Coupling of 2 with several terminal alkynes gave 5-(alkyn-1-yl)uracil derivatives (9), which underwent tosylation to produce the targeted 5-(alkyn-1-yl)-1-(p-toluenesulfonyl)uracil compounds (11). Copper(I)-catalyzed cyclization of 9 gave the respective furopyrimidines (10) in low yields. Again, cyclization did not occur with the tosyl derivatives (11). Activity against varicella-zoster virus (VZV) was observed with longer-chain analogues of 9 and 11, and compound 7 showed activity against human cytomegalovirus (HCMV) at near cytotoxic levels.Key words: antiviral screening, furo[2,3-d]pyrimidin-2(3H)-one derivatives, Sonogashira coupling, 1-(p-toluenesulfonyl)pyrimidine derivatives.

  5-iodouracil (2) 与三甲基硅基乙炔的 Sonogashira 偶联得到 5-(三甲基硅乙炔基)脲嘧啶 (3)，经脱保护后得到 5-乙炔基脲嘧啶 (4)。在铜（I）催化下，4 环化得到呋喃并[2,3-d]嘧啶-2(3H)-酮（5）。对 2 和 4 进行对甲苯磺酰基化反应，分别得到 1-（对甲苯磺酰基）衍生物 6 和 7。对甲苯磺酰化的化合物 6 和三甲基硅基乙炔没有发生 Sonogashira 偶联反应，也没有发生铜（I）催化的 7 环化反应。2 与几种末端炔烃偶联后得到 5-(炔-1-基)尿嘧啶衍生物 (9)，这些衍生物经过对甲苯磺酰基化反应生成目标 5-(炔-1-基)-1-(对甲苯磺酰基)尿嘧啶化合物 (11)。在铜(I)催化下，9 的环化反应以低产率生成了相应的呋喃嘧啶（10）。同样，甲苯磺酰基衍生物也没有发生环化反应（11）。9 和 11 的长链类似物对水痘-带状疱疹病毒（VZV）具有活性，化合物 7 对人类巨细胞病毒（HCMV）具有接近细胞毒性水平的活性。
