An enantioselective one-pot catalytic strategy to dihydroquinoxalinones, featuring novel 1-phenylsulfonyl-1-cyano enantioenriched epoxides as masked α-halo acyl halide synthons, followed by a domino ring-opening cyclization (DROC), is documented. A popula

The use of less basic chiral amine catalysts for highly enantioselective conjugate additions of aldehydes to vinyl sulfones was reported. The results show that the addition of aldehydes to α-cyano vinyl sulfones takes place at -40°C to give alcohols. The

The inexpensive natural phosphate, both alone and doped with potassium fluoride, is a new basic catalyst for the synthesis of α,β- unsaturated arylsulfones. Activation by water and benzyltriethylammonium chloride has also been investigated. When using an
Na2CaP2O7, a new catalyst for the synthesis of unsaturated arylsulfones
Zahouily, Mohamed,Salah, Mohamed,Bennazha, Jamal,Rayadh, Ahmed,Sebti, Sa?d

The synthetic diphosphate Na2CaP2O7 is a new basic catalyst for the synthesis of unsaturated arylsulfones. The condensation was carried out under mild conditions at room temperature in methanol or ethanol. The optimum of t
