Cationic Ir/Me-BIPAM-catalyzed asymmetric intramolecular direct hydroarylation of α-ketoamides.
    Angewandte Chemie (International ed. in English), 2014, Mar-03, Volume: 53, Issue:10

    Asymmetric intramolecular direct hydroarylation of α-ketoamides gives various types of optically active 3-substituted 3-hydroxy-2-oxindoles in high yields with complete regioselectivity and high enantioselectivities (84-98% ee). This is realized by the use of the cationic iridium complex [Ir(cod)₂](BAr(F)₄) and the chiral O-linked bidentate phosphoramidite (R,R)-Me-BIPAM.

Me-BIPAM for the synthesis of optically active 3-aryl-3-hydroxy-2-oxindoles by ruthenium-catalyzed addition of arylboronic acids to isatins.
    Chemistry, an Asian journal, 2012, Volume: 7, Issue:10

    A chiral O-linked C(2)-symmetric bidentate phosphoramidite (Me-BIPAM) was found to be efficient for the ruthenium-catalyzed addition of arylboronic acids to isatins. Asymmetric synthesis of 3-aryl-3-hydroxy-2-oxindoles by 1,2-addition of arylboronic acids to isatins was carried out in the presence of [RuCl(2)(PPh(3))(3)]/(R,R)-Me-BIPAM and KF, resulting in an enantioselectivity as high as 90 % ee. It was found that the reaction with N-protected isatins proceeds with high yields and good enantioselectivities. The best protective groups on the nitrogen atom were different depending on the substituents on the aromatic ring. The use of a N-benzyl group resulted in excellent enantioselectivities in many substrates compared with other groups.
