4-Vinylbenzyl analogs of adenine and uracil: reactive monomers for nucleobase polymeric resins

S. G. Srivatsan, S. Verma and M. Parvez

Abstract: The crystal structures of 9-(4-vinylbenzyl)adenine, C₁₄H₁₃N₅, and 1-(4-vinylbenzyl)uracil, C₁₃H₁₂N₂O₂, are composed of zigzag ribbon-like structures that are stabilized by conventional (N-HN-type) hydrogen bonds for the former and conventional (N-HO-type) and non-conventional (C-HO-type) hydrogen bonds for the latter; the hydrogen-bonding patterns are represented by graph-sets R(9) and R(8), respectively. The adenine and uracil moieties in these alkylated derivatives are planar and are inclined at angles of 84.44 (4) and 79.07 (7)°, respectively, with respect to the phenyl rings.

Formula: C₁₄H₁₃N₅ and C₁₃H₁₂N₂O₂
