Click ‘n’ chips: Azide and alkyne‐bearing sialic acids (purple diamond; see picture) were subjected to high‐throughput click chemistry to generate a library of sialic acid analogues. Microarray printing of the library and screening with the siglec family of sialic‐acid‐binding proteins, led to the identification of high‐affinity ligands for siglec‐9 and siglec‐10.
Multidimensional reaction screening with complex cycloheptane-1,2-diones is described. The studies resulted in the discovery of regioselective Lewis acid mediated condensation reactions with substituted ureas, and a diastereoselective hydrogenation process that proceeds through an interesting isomerization of allylpalladium hydride.
