Starch, one of the most abundant natural polymer was used as support for chiral pyridine-bis(oxazoline) ligand. The corresponding ruthenium complex was used as catalyst in cyclopropanation reaction of styrene with Et diazoacetate. Yield, diastereoisomeric excess and enantiomeric excess kept const. after 3 runs.
