In the presence of 25 mol% of polymer-supported chiral sulfonamide, a variety of β-keto sulfones can be reduced into the corresponding β-hydroxy sulfones in excellent yields and with high enantioselectivities using the reducing system of NaBH 4 /Me

The addition reaction of bromodifluoroacetate with the electron-deficient alkene — gem -dicyanoalkene was promoted smoothly by titanium biscyclopentadienyl dichloride (Cp 2 TiCl 2 )/Zn system in a THF solvent under mild conditions in moderate to go
