Abstract
N-acetyl-galactosamine appended amino acid esters, the new biomaterials are hydrogels formed through the supramolecular assembly in water. They consist of small molecule with hybrid structure. At one end, these molecules contain a polar moiety that is hydrophobic due to its favourable interaction with water and at the other end, two non-polar moieties forming a hydrophobic group are linked through an aminoacetate unit. These materials possess extremely high affinity towards water molecules, and thus the ability to form hydrogel at very low concentrations creating a dense network of nanofibres. This review summarises the combinatorial approach used for the synthesis of these novel materials, screening and optimization, and their applications.
Keywords: supramolecular polymers, xerogels, combinatorial synthesis, organogelators, hydrolysis

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
