Dendrimers are highly branched three-dimensional macromolecules with a highly controlled structure, a single molecular weight, numerous controllable dendritic branches and peripheral functionalities, as well as the tendency to adopt an ellipsoid or spheroid shape once a certain size is reached. These features have made them attractive for application in pharmaceutical and medicinal chemistry in gene transfection, as Read More

Heterocyclic compounds are the largest and most diverse family of organic compounds. Among them, aromatic heterocyclic compounds are the structural motifs found in a great number of biologically active synthetic and natural compounds, agrochemicals, and medicines. Moreover, aromatic heterocyclic compounds are extensively utilized for the formation of dyes and polymeric materials of great importance. In org Read More

In recent years, diaryliodonium salts have been extensively exploited as green, efficient electrophilic arylation reagents in a large range of organic synthesis. These arylating reagents exhibit relatively high reactivity and good selectivity in many transformations. In this review, the synthetic methods towards diaryliodonium salts are described briefly, and the research progress in arylation reactions by using diaryliodoniums in Read More

Oxindoles are an important class of heterocyclic scaffolds widely present in natural products and bioactive compounds. For this reason, a plethora of methodologies for the stereoselective synthesis of enantioenriched oxindoles has been studied over the years. Among all the reported synthetic strategies, organocatalysis has proven to be a powerful tool for the asymmetric synthesis of this class of compounds being a step- and a Read More

Herein, the synthesis of 6-deoxygenated α(1→4)-oligoglucans via thermostable α- glucan phosphorylase (from Aquifex aeolicus VF5)-catalyzed enzymatic chain-elongation is reported from a maltotriose primer using a non-native substrate, 6-deoxy-α-D-glucose 1- phosphate. The enzymatic reaction of the two substrates mainly produced a tetrasaccharide with one 6-deoxy-α-D-glucose unit at the non-reducing end, together Read More
