Crystal structure of 5-(1,3-dithian-2-yl)-2H-1,3-benzodioxole
In the title compound, C11H12O2S2, two independent but virtually superimposable mol-ecules, A and B, comprise the asymmetric unit. In each mol-ecule, the 1,3-di-thiane ring has a chair conformation with the 1,4-disposed C atoms being above and below the plane through the remaining four atoms. The substituted benzene ring occupies an equatorial position in each case and forms dihedral angles of ...

The title compound, C19H22N2O3, {systematic name (1aR,4E,7aS,8E,10aS,10bR)-1a,5-dimethyl-8-[(pyrimidin-5-yl)-methylid-ene]-2,3,6,7,7a,8,10a,10b-octa-hydro-oxireno[2',3':9,10]cyclo-deca-[1,2-b]furan-9(1aH)-one} was obtained from the reaction of parthenolide [systematic name (1aR,7aS,10aS,10bR,E)-1a,5-dimethyl-8-methyl-ene-2,3,6,7,7a,8,10a,10b-octa-hydro-oxireno[2',3':9,10]cyclodeca-[1,2-b]furan-...
متن کامل5-(1H-Inden-2-yl)-1,3-benzodioxole
In the title compound, C(16)H(12)O(2), the non-H atoms are coplanar with a mean r.m.s. deviation of 0.0260 (2) Å. The deviations of the bond angles from normal values at the indenyl junction C atom and the indenyl bridgehead C atom nearest the junction are imposed by the five-membered ring geometry. Due to conjugation, the single bond linking the two ring systems [1.455 (3) Å] is significantly ...
متن کاملCrystal structure of methyl 2-[5-(2-hydroxyphenyl)-2H-tetrazol-2-yl]acetate
The title compound, C10H10N4O3, was synthesized by the esterification of hy-droxy-phenyl tetra-zole. There is an intra-molecular O-H⋯N hydrogen bond present involving the hy-droxy group and the tetra-zole ring. The tetra-zole ring is inclined to the phenol ring by 2.85 (13)°, while the methyl acetate group is almost normal to the tetra-zole ring, making a dihedral angle of 82.61 (14)°. In the c...
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...
