Bis(oxazoline)-Based Coordination Polymers: A Recoverable System for Enantioselective Henry Reactions
An efficient releaseācapture strategy for the
recovery and
reuse of enantioselective catalysts in the Henry reaction is described.
This strategy is based on the precipitation of an insoluble coordination
polymer at the end of each reaction, allowing easy separation from
products. The coordination polymer is formed through aggregation of
CuĀ(II) ions with ditopic bisoxazoline-based chiral ligands. Up to
11 catalytic cycles have been conducted keeping good yields and enantioselectivities
