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

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-H···N-type) hydrogen bonds for the former and conventional (N-H···O-type) and non-conventional (C-H···O-type) hydrogen bonds for the latter; the hydrogen-bonding patterns are represented by graph-sets R²₂(9) and R²₂(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.
