Cobalt catalyzed C-P bond formation by cross-coupling of boronic acids with P(O)H compounds in presence of zinc
In our current work, we have reported the first cobalt-catalyzed cross-coupling of arylboronic acid with alkyl/aryl phosphites under mild conditions. The reaction was carried out in the presence of zinc powder as an additive and ter-pyridine as a ligand. The use of non-precious cobalt salt makes the protocol advantageous, as it is inexpensive and more abundant than the previously used methods where precious metal salts (Pd and Pt) were used. The reaction has a wide substrate scope and the products were obtained in good yields.
Phosphorus analogues of γ-aminobutyric acid, a new class of anticonvulsants
A series of phosphorus compounds, designed as analogues of γ-aminobutyric acid (GABA) in that they possess a P=O moeity separated by three atoms from an amino or acetamido group, was synthesized and tested by using in vitro GABA(A) and GABA(B) receptor bi
