An efficient synthesis of indane-derived bis(oxazoline) and its application to hetero Diels–Alder reactions on polymer support

Indane-derived bis(oxazolines) were synthesized in two steps and 93% overall yield starting from commercially available substrates. This ligand is as effective as tert-butyl bis(oxazoline) in hetero Diels–Alder reaction both in solution and on polymer support.
