5-Azido-4-benzyloxy-2-methoxy-6-methylperhydropyran-3-ol
In the title compound, C(14)H(19)N(3)O(4), the perhydro-pyran ring adopts a chair conformation. An intra-molecular C-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal packing, mol-ecules are linked by O-H⋯O hydrogen bonds, forming infinite chains along [100].
متن کاملCrystal structure of 7-{[bis(pyridin-2-ylmethyl)amino]methyl}-5-chloroquinolin-8-ol
In the title compound, C22H19ClN4O, the quinolinol moiety is almost planar [r.m.s. deviation = 0.012 Å]. There is an intra-molecular O-H⋯N hydrogen bond involving the hy-droxy group and a pyridine N atom forming an S(9) ring motif. The dihedral angles between the planes of the quinolinol moiety and the pyridine rings are 44.15 (9) and 36.85 (9)°. In the crystal, mol-ecules are linked via C-H⋯O ...

In the title compound, C(15)H(12)FN(3)O(3)·CH(3)OH, the dihedral angle between the quinazoline ring system and the benzene ring is 81.18 (9)°. In the crystal, mol-ecules are linked by N-H⋯O and O-H⋯N hydrogen bonds, generating [10-1] chains of alternating main mol-ecules and solvent mol-ecules. Weak C-H⋯O inter-actions are also observed.
متن کاملSynthesis, Radioiodination and Biodistribution Evaluation of 5-(2-amimo-4-styryl pyrimidine-4-yl)-4-methoxybenzofuran-6-ol
This study describes the organic synthesis of 5-(2-amimo-4-styryl pyrimidine-4-yl)-4-methoxy benzofuran-6-ol (SPBF) as an example of a benzofuran derivative used as a new series of amyloid imaging agents. These benzofuran derivatives may be useful amyloid imaging agents for detecting B-amyloid plagues in the brain of Alzheimer’s disease. The precursor is 1-[6-hydroxy-4-methoxybenzofuran-5-yl]-p...
متن کاملCrystal structure of 1-(5-amino-2H-tetrazol-2-yl)-2-methylpropan-2-ol
The title compound, C5H11N5O, crystallized with two independent mol-ecules in the asymmetric unit. The two mol-ecules differ in the orientation of the 2-methyl-propan-2-ol unit, with the hy-droxy H atoms pointing in opposite directions. In the crystal, mol-ecules are linked via O-H⋯O and N-H⋯O hydrogen bonds, forming ribbons propagating along [10-1]. The ribbons are linked via N-H⋯N hydrogen bo...
