Abstract:

2-oxazolines are known for a long time but only recently studies concerning their use as catalyst for asymmetric synthesis have gained enormous attention. The synthesis of copolymers involving 2-oxazoline ring-monomers is known. Functionalized 2- oxazoline-homopolymers presents different medicinal and biological applications. In this study we present the synthesis of optically active alkynyl-pyridyl-oxazoline monomers to be used as precursors of helical polymers. Depending on the nature of the substituent attached to the arylacetylenic unity helical preferentially oriented (P or M) polymers can be obtained. These kind of helical polymers may be employed in the molecular and/or ion recognition. Moreover the polymers containing the pyridyl-oxazoline unity will be employed for metal complexation and the resulting organometallics will be explored for recoverable catalysts.
