Stereoregular polymerizations have attracted great attention since the first report reported by Natta to prepare isotactic polyprolylene. Given the almost limitless opportunities of ligand/metal combinations, it is not surprising that transition metal and organometallic catalysts have dominated the field. Nevertheless, their substantial toxicity and sensitivity is accelerating the development of organic catalysts to replace metal based catalysts in sensitive applications, such as biomedical or microelectronics. To date, some organic catalysts have shown the ability to promote stereocontrolled polymerization. However, none of them showed the ability to transfer the chirality from catalyst to polymer and promote different stereochemical outcomes by modifying the chirality of the catalyst. In this work we report for the first time the chirality transfer from a fully organic based catalyst to the polymer using proline based catalytic system.
