Supramolecular Thermo Aero-able Gelators (STAGs) for synthesis of hydrogels

open access: yes, 2012
Supramolecular Thermo Aero-able Gelators (STAGs): tartaric acid, urea, and guanidine with amide and imine moieties as supramolecular synthons are introduced to cross-link and aerate ('aero-able') polyacrylate networks for synthesis of hydrogels. They are

Crystal structure of the N-benzyloxycarbonyl-Alanyl-Phenylalanyl-methyl ester: the importance of the H-bonding pattern [PDF]

open access: yes, 2011
Large crystals of the methyl ester of the N-a-benzyloxycarbonyl protected Ala-Phe dipeptide (Z-AF-OMe) were obtained after the very slow evaporation of a solution of the corresponding carboxylic acid (Z-AF-OH) in methanol containing an excess of HCl. The

Supramolecular synthons, tectons, and crystal structures of noncovalent organic frameworks

open access: yesChemical Physics Reviews
In reticular chemistry, framework structures formed from organic molecules by noncovalent intermolecular interactions [i.e., noncovalent organic frameworks (nCOFs)] have been intensively investigated over the last two decades as another type of candidate

One‐Pot Ruthenium‐Catalyzed Synthesis of Benzyl/Allyl‐Halide Substituted (dihydro)naphthalenes via Radical Benzannulation

open access: yesChemistryEurope, EarlyView.
A one‐pot protocol to synthesize reactive benzyl‐ and allyl‐halide‐substituted (dihydro)naphthalenes from 2,3‐aryl‐1,3‐butadiene substrates and halogenated alkanes has been developed, using [Cp*RuCl(PPh3)2] as the catalyst. Mechanistic studies revealed an atom transfer radical addition and radical benzannulation sequence, followed by HCl elimination ...
