  Synthesis and structural evidence for new diimidazo-[1,5-a:1′,5′-d] pyrazinediones

  摘要：

  The synthesis of derivatives of 5H, 10H-diimidazo [1,5-a: 1',5'-d] pyrazine-5,10-dione is described. The mechanism of the reaction is discussed and the chemical, spectral and X-ray data giving the evidence of the structure of these compounds are presented. X-ray studies were carried out on compound 6c (C24H22N6O2) with a = 9.250(3), b = 11.879(3), c = 10.250(3), Z = 2 and space group P2(1)/a. The structure was solved using direct methods and refined by weighted full-matrix least squares. The refinement, based on 990 reflections with I greater-than-or-equal-to 2.5 sigma(I), converged to a final R of 0.041 and R(w) = 0.036.
