A convenient and efficient synthesis of multi-substituted dihydropyrano[2,3-c]pyrazole derivatives is reported. The four-component reaction of 4-hydrazinobenzoic acid, β-keto esters, aromatic aldehydes, and malononitrile using 10 mol% CAN catalyst in water under ultrasound irradiation produced the target compounds in good-to-excellent yields.

Glycan recognition leading to cell-cell interactions, signaling, and immune responses is mediated by various glycan-binding proteins (GBPs) showing highly diverse ligand specificities. We describe here a rapid glycan immobilization technique via 4-hydrazinobenzoic acid (HBA)-functionalized beads and its application to high-throughput
