Abstract
The enantioselective conjugate addition reaction of 3-substituted
oxindoles with 1,1-bis(benzenesulfonyl)ethylene by binaphthyl-modified
bifunctional organocatalysts was investigated. The corresponding
Michael adducts, containing a quaternary center at C3 position of
the oxindoles, were generally obtained in high yields with excellent
enantioselectivities (up to 99% ee).
Key words
oxindole - vinyl sulfone - conjugate addition - bifunctional organocatalysis - asymmetric catalysis

Typical Procedure
for the Conjugate Addition Reaction of 3-Phenyl Oxindole 1f with
Vinyl Sulfone 2
To a solution of 3-phenyl oxindole 1f (0.3 mmol, 92 mg) and catalyst VIII (0.03 mmol, 21.4 mg) in CH2Cl2 (1.2
mL) was added 1,1-bis(benzenesulfonyl)ethylene (2,
0.45 mmol, 138.7 mg). Reaction mixture was stirred for 6 h at r.t., concentrated,
and purified by flash column chromatography (EtOAc-hexane = 1:5)
to afford the Michael adduct (3f, 168 mg,
90%).
