4-Vinylbenzyl analogs of adenine and uracil: reactive monomers for nucleobase polymeric resins.
The crystal structures of 9-(4-vinylbenzyl)adenine, C(14)H(13)N(5), and 1-(4-vinylbenzyl)uracil, C(13)H(12)N(2)O(2), are composed of zigzag ribbon-like structures that are stabilized by conventional (N[bond]H...N-type) hydrogen bonds for the former and conventional (N[bond]H...O-type) and non-conventional (C[bond]H...O-type) hydrogen bonds for the latter; the hydrogen-bonding patterns are represented by graph-sets R(2)(2)(9) and R(2)(2)(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) degrees, respectively, with respect to the phenyl rings.
