bis(sulfonamide)−diamine (BSDA) ligands were synthesized from commercially available chiral α-amino alcohols and diamines. The chiral BSDA ligand 3a, coordinated with Cu(I), catalyzes the enantioselective Henry reaction with excellent enantioselectivity (up to 99%). Moreover, with the assistance of pyridine, a CuBr−3a system promotes the diastereoselective Henry reaction with various aldehyde substrates

UiO-68 isoreticular zirconium metal–organicframework (MOF) with mixed dicarboxylate struts by utilizing a microwave-assisted heating method. It can work as an efficient hydrogen-bond-donating heterogeneous catalyst for Henry reactions of benzaldehydes and nitroalkanes. This mixed strut MOF exhibits improved catalytic activity compared to the pure urea-functionalized linker based analogue.
