Organic Reactions in Water: A Distinct Novel Approach for an Efficient Synthesis of α-Amino Phosphonates Starting Directly from Nitro Compounds

Synthesis and structural characterization of homochiral 2D coordination polymers of zinc and copper with conformationally flexible ditopic imidazolium-based dicarboxylate ligands

Chiral imidazolium-based dicarboxylate ligands behave as bridging ditopic linkers capable of forming 2D coordination polymers with zinc and copper metals.

2,6-Dimethylphenol derived H-phosphonate and α-hydroxyphosphonate: facile synthesis, crystal chemistry, supramolecular association and metal complexation

A H-phosphonate and an α-hydroxyarylphosphonate with active P–H and P–OH groups have been synthesized from 2,6-dimethylphenol and their aggregation behavior has been investigated.

n-BuLi as a highly efficient precatalyst for hydrophosphonylation of aldehydes and unactivated ketones

It was found for the first time that organic alkali metal compounds serve as highly efficient precatalysts for the hydrophosphonylation reactions of aldehydes and unactivated ketones with dialkyl phosphite under mild conditions. For ketone substrates, a reversible reaction was observed, and the influence of catalyst loading and reaction temperature on the reaction equilibrium was studied in detail. Overall, the hydrophosphonylation reactions catalyzed by 0.1 mol % n-BuLi were completed within 5 min for a broad range of substrates and generated a series of α-hydroxy phosphonates in high yields.

Synthesis of Cyclic α-Aminophosphonates through Copper Catalyzed Enamine Activation

A copper-catalyzed tandem cyclization triggered addition strategy that relies on electrophilic enamine activation has been used to synthesize various cyclic α-aminophosphonates derivatives in good to excellent yields. Both five and six membered rings can be generated under mild conditions with high regioselectivity. A mechanism based on copper catalyzed enamine activation is proposed.
