  Synthesis and theoretical studies on energetics of novel N- and O- perfluoroalkyl triazole tagged thienopyrimidines – Their potential as adenosine receptor ligands

  摘要：

  A series of novel N- and O- perfluoroalkyl triazole tagged thienopyrimidines 6a-c and 7a-d was synthesized in two steps from thienopyrimidin-4-ones 2 through O- and N-propargylated regioisomers 3a-i and 4a-i respectively. Compound 2 was reacted with propargyl bromide to form O- and N-propargylated regioisomers 3 and 4 in definite proportions. Each regioisomer was separated and independently subjected to [3 + 2] cycloaddition using perfluoroalkyl azides through Click reaction under Sharpless conditions and obtained exclusively anti product in each case. The formation of two regioisomers in the first step and single anti addition product in the next step could be explained based on computational studies carried out at B3LYP/6-31G(d) level of theory. Results of Fukui function indices at the reactive centers are in accordance with the observations. On evaluation of the synthesized molecules for their binding affinities towards adenosine receptors, 4d and 4f were found to be selective to A(1) over A(2A) receptors. (C) 2010 Elsevier Masson SAS.
