Efficient Polymer-Supported Sharpless Alkene Epoxidation Catalyst

open access: yesMolecules, 1998
Homogeneous linear poly(tartrate ester) ligands provide high chemical yields and enantiomeric excesses in the epoxidation of trans-hex-2-en-1-ol using Ti(OPri)4-tert-butyl hydroperoxide.

Dust evolution, a global view: IV. Tying up a few loose ends [PDF]

open access: yesarXiv, 2018
This work is an attempt to tie together some of the, seemingly disparate, loose ends from the preceding papers in this series into the global view of dust evolution in the interstellar medium. In particular, the nature of the hydro-carbonaceous, infrared absorption and emission band carriers is discussed within the context of a simple poly- hexa-cyclic

Topological Influence of Sextets on Graphene Oxide Nanostructure [PDF]

open access: yesarXiv
Graphene Oxide (GO) remains a perennial chemical enigma despite its utility in preparing graphene and its functionalization. Epoxides and tertiary alcohols are construed as primary functional groups, but the structural motifs, spectra, and physicochemical properties remain largely inexplicable. Our graph theoretic perturbational analysis of introducing

Synthesis of an Epoxide for TMM Cycloadditions [PDF]

open access: yes, 2013
In order to produce a highly functionalized five-membered ring useful for further synthetic processes via Palladium catalysis, a series of precursors need to be synthesized in order to form the epoxide used in cyclic formation.

Recent progress in the synthesis of six-membered aminocyclitols (2008-2017) [PDF]

open access: yes, 2018
Aminocyclitols are of interest as glucosidase inhibitors, as probes for the study of pseudoglycosyltransferases, and as potential therapeutics for the treatment of Gaucher’s disease.
