1-(β-D-Ribofuranosyl)-6-propylcytosine

The conformation of the title compound, C₁₂H₁₉N₃O₅, in the solid state is syn, and the ribose ring is close to the ⁴E envelope conformation. The propyl side chain is planar and almost coplanar with the cytosine ring, the deviation between the two being 4.4 (2)°. Hence the overall structure consists essentially of two planes perpendicular [86.2 (2)°] to each other, the plane of the sugar moiety and that of the 6-propylcytosine.
