Molecular Structures of Cyclohexane Derivatives. III

Molecular and Crystal Structures of Three Berberine Derivatives

Berberine azide, berberine thiocyanate, and 8-cyano-8H-berberine were prepared from berberine chloride, a quaternary protoberberine alkaloid. The molecular and crystal structures of all compounds are reported and discussed.

The Molecular and Crystal Structures of Galvinol Derivatives

Galvinols are interesting, sterically hindered compounds that serve as precursors for the generation of stable galvinoxyl radicals. In order to elucidate their basic structural chemistry and the influence of steric effects on their conformation a comparative analysis of several galvinol derivatives was undertaken. The aryl and quinoid subunits could clearly be identified and substituents at the...

Molecular Caging of Graphene with Cyclohexane: Transfer and Electrical Transport

Transfer of large, clean, crack- and fold-free graphene sheets is a critical challenge in the field of graphene-based electronic devices. Polymers, conventionally used for transferring two-dimensional materials, irreversibly adsorb yielding a range of unwanted chemical functions and contaminations on the surface. An oil-water interface represents an ideal support for graphene. Cyclohexane, the ...

Responsive cyclohexane-based low-molecular-weight hydrogelators with modular architecture.

Antibacterial properties of 3 H-spiro[1-benzofuran-2,1'-cyclohexane] derivatives from Heliotropium filifolium.

A re-examination of cuticular components of Heliotropium filifolium allowed the isolation of four new compounds: 3'-hydroxy-2',2',6'-trimethyl-3H-spiro[1-benzo-furan-2,1'-cyclohexane]-5-carboxylic acid(2), methyl 3'-acetyloxy-2',2',6'-trimethyl-3H-spiro[1-benzofuran-2,1'-cyclohexane]-5-carboxylate (3), methyl 3'-isopentanoyloxy-2',2',6'-trimethyl-3H-spiro[1-benzofuran-2,1'-cyclohexane]-5-carbox...
