Heparin Binding Induced Supramolecular Chirality into Self-Assembly of Perylenediimide bolaamphiphile Chirality is one of the hallmark of biomolecules. Here we utilize heparin, a chiral biomolecule and a potent drug, to induce chiral organization into the assembly of achiral molecule. Polyanionic heparin binds with dicationic perylenediimide derivative to induce supramolecular helical organization in aqueous medium as well as in a highly competitive cell culture medium.

Supported Pd-catalyzed ring opening and chemoselective aminocarbonylative coupling of benzoxazoles with aryl iodides† A tandem approach using polystyrene-supported palladium (Pd@PS) nanoparticles (NPs) catalyzed aminocarbonylative coupling of benzoxazole with aryl iodides to synthesize N-(2-hydroxyphenyl)benzamides has been devised. This protocol involves the ring opening of benzoxazole to 2-aminophenol followed by aminocarbonylative coupling with aryl iodides.
