Optical microscopy and multi-particle tracking are used to study hydrodynamic interactions of monodisperse polymethylmethacrylate (PMMA) spheres at a decalin– water interface. The short-time self-diffusion coefficient measured at low surface coverage has the form D S (n)=αD0(1−βn), where n is the area fraction occupied by the particles, and D0 is the Stokes–Einstein diffusion coefficient in the...

The molecular weight dependence of the radii of gyration Rg in a Θ solvent (trans-decalin) of one regular branched comb and three regular centipede polystyrenes was studied using a gel permeation chromatography system equipped with a two-angle light scattering detector and a refractive index detector. Rg in trans-decalin for each sample of particular molecular weight was about 25% smaller than ...

Fusarielins are polyketides with a decalin core produced by various species of Aspergillus and Fusarium. Although the responsible gene cluster has been identified, the biosynthetic pathway remains to be elucidated. In the present study, members of the gene cluster were deleted individually in a Fusarium graminearum strain overexpressing the local transcription factor. The results suggest that a...

A highly congested decalin embodying an alpha-methylene ketone is synthesized in 11 steps from the Wieland-Miescher ketone and efficiently converted to the polycyclic frameworks of anominine and tubingensin A, which constitutes the first approach to the skeleton of these indole diterpenoids.
