trans-Adenosine 3',5'-cyclic N,N-dimethylphosphoramidate ether solvate
crystallizes as monoclinic prisms elongated about the b-axis. The dio
xaphosphorinane ring adopts a flattened chair conformation with an alm
ost planar dimethylamino substituent equatorial. The purine ring confo
rmation is anti. The ribose ring exists in a T-3(4) conformation.
