  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.

  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.

  Bicyclic furanopyrimidines were recently discovered by us to be potent and selective inhibitors of VZV. Related studies to investigate the role of the sugar in this activity uncovered dideoxy furanopyrimidines as inhibitors of HCMV and this led to the preparation of highly modified long alkyl chain furanopyrimidines from the N- and O-alkylation of their parent bases. Herein we describe their synthesis and subsequent biological evaluation against HCMV. O-alkylated derivatives were almost invariably found to be at least equiactive with their N-alkylated counterparts. At this point, little change in activity has been found with large variation in N- and O-substituent.

  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.
