| In addition to making new molecules, sometimes we are interested in making new reactions. In some cases we are trying to design unique catalysts to help carry out difficult transformations. In other applications we are trying to control specificity through intermolecular cooperative interactions. We are tackling some important synthetic processes, reinventing ways of performing functional group transformations within the framework of Green Chemistry. A normally unselective process can be made more selective by the use of self assembly and catalysis patterned after the mechanisms that enzymes use to enhance reactions in living systems. Leading to the easy and cost effective synthesis of important medicinal products like Sceptrin, an antibiotic, antimicrobial, antimuscarinic found in minute quantities in the sea sponge family Agelas. Novel reagents attached to fixed substrates become inherently non-toxic, as in the development of polymeric spiropyrans. Sometimes these immobilized reagents can be used to turn an expensive, wasteful reaction into a benign and cost effective catalytic reaction. In other instances, entirely new properties become apparent when reactive surfaces are examined. The synthesis of many products can be done in the solid state—requiring no solvent and ambient conditions. The reaction is made more environmentally benign with the use of smaller batches, better solvents, and recirculating cooling baths during the testing stages. |
