Catalytic asymmetricbenzoylation of 1,2-diols has been developed using a solid-phase asymmetriccatalyst. The reaction conditions were optimized by the screening of different metal salts, solvents, bases, and temperatures. High-throughput screening was performed using circular dichroism detection, and the results revealed that Nb-imidazoline-copper(I) in combination with diisopropylethylamine was
