Organic letters, 15(8), 1846-1849 (2013-04-09)
An asymmetric organo- and gold-catalyzed one-pot sequential Mannich/hydroamination reaction has been developed. Using this protocol, spiro[pyrrolidin-3,2'-oxindole] derivatives were synthesized in good yields (up to 91%) and excellent enantioselectivities (up to 97% ee).

Organic letters, 13(1), 82-85 (2010-12-09)
The first tertiary amine catalyzed enantioselective Morita-Baylis-Hillman (MBH) reaction of isatins with acrylates has been demonstrated, allowing asymmetric synthesis of biologically significant 3-substituted-3-hydroxy-2-oxindoles in good yields and with excellent enantioselectivities. The C6'-OH group of β-isocupreidine (β-ICD) is believed to facilitate

Chemical communications (Cambridge, England), 46(36), 6822-6824 (2010-08-21)
A copper-catalyzed addition of arylboronates to isatins has been developed to give 3-aryl-3-hydroxy-2-oxindoles under mild conditions. The catalytic cycle of this process has been examined through a series of stoichiometric reactions and an effective asymmetric variant has also been described

Organic letters, 14(9), 2210-2213 (2012-04-14)
The reaction of phenyliodine bis(trifluoroacetate) (PIFA) with a series of anilides 1 (E = CO(2)Et) in CF(3)CH(2)OH was found to give 3-hydroxy-2-oxindole derivatives 2, while that with various anilides 1' (E = CON(R(4))Ar) afforded the C(2)-symmetric or unsymmetric spirooxindoles 3.

Chemistry (Weinheim an der Bergstrasse, Germany), 16(22), 6632-6637 (2010-04-22)
A highly enantioselective alpha-amination of 3-substituted oxindoles with azodicarboxylates catalyzed by a chiral Sc(OTf)(3)/N,N'-dioxide complex (Tf: triflate) has been developed and affords the corresponding 3-amino-2-oxindole derivatives in high yields (up to 98%) with excellent enantioselectivities (up to 99% ee).
