The molecule of the title compound, C20H34O4, is centrosymmetric. In the crystal structure, a network of O—H...O hydrogen bonds result in each molecule being linked to four neighbouring molecules and a two-dimensional net is formed. [ABSTRACT FROM AUTHOR]

The title compound, C8H12O3, was synthesized to prove the relative configuration in the projected total synthesis of curvicollides A–C. In the crystal structure, molecules are linked via a bifurcated O—H...O hydrogen bond and a chain of molecules is formed along the a axis. [ABSTRACT FROM AUTHOR]

The crystal structure of the title compound, C11H12O, a substrate for gold-catalysed cyclo­isomerization reactions [Hoffmann-Röder & Krause (2001). Org. Lett. 3, 2537–2538], contains two mol­ecules in the asymmetric unit. There are two inter­molecular O—H ⋯ O hydrogen bonds in the crystal structure and a chain of mol­ecules is formed along the c axis via these hydrogen bonds. [ABSTRACT FROM AUTHOR]

In the title compound, C14H30O4Si, the bond angles around Si are in the range 105.4 (3)–112.1 (4)° and the tetra­hydro­furan ring adopts a distorted envelope conformation. There is one intra­molecular and one inter­molecular O—H⋯O hydrogen bond in the crystal structure. A spiral of mol­ecules forms around the 41 axis ( c axis) of the crystal structure via the inter­molecular O—H⋯O hydrogen bond. [ABSTRACT FROM AUTHOR]

The crystal structure of the title compound, C19H17F3N2O4, a metabolite of the fungicide trifloxy­strobin (TFS), contains one mol­ecule in the asymmetric unit. The CF3 group is disordered over two positions. The important characteristics of the mol­ecule are the two C=N bonds in an E,E configuration, one in the β-methoxy system and the other in the oxy­methyl side chain between the two aromatic rings. The mol­ecules are linked via an O—H⋯N hydrogen bond and an infinite spiral is formed along the b-axis direction. [ABSTRACT FROM AUTHOR]
