Some hindered chiral 1, 3-diketones were successfully synthesized from the reaction of (+)-3α-bromocamphor with acyl chlorides in the presence of samarium diiodide (SmI2) under mild reaction conditions in high yields.

NMR and VIS titration studies. The polymersimprinted with the template demonstrated enantioselectiverecognition of the corresponding template structure, and induced a 55-fold enhancement of the rate of reaction of camphor (1) with benzaldehyde (2), relative to the solution reactions, and were also compared to reactions with a series of reference polymers. Substrate chirality was observed to influence
