  A highly predictive model to correlate the steric and electronic parameters of tertiary amine thiourea catalysts with the stereoselectivity of Michael reactions of 3‐substituted benzofuranones and alkyl 2‐phthalimidoacrylates is described. As predicted, new 3,5‐bis(trifluoromethyl)benzyl‐ and methyl‐substituted tertiary amine thioureas turned out to be highly suitable catalysts for this reaction and

  A chiral bicyclic guanidine-catalyzed enantioselective sulfenylation of 3-substituted oxindoles to N-(sulfanyl)-succinimides has been developed. A series of unprecedented 3-sulfenylated oxindoles, such as 3-benzyl/alkyl-substituted 3-benzyl/alkyloxindoles, were obtained with high enantioselectivities (up to 98% ee). This methodology is also effective for the first asymmetric sulfenylation of benzofuran-2(3H)-ones, providing 3-benzyl-3-benzylthio-substituted benzofuran-2(3H)-ones with satisfactory results (up to 95% ee).

  日期：2015.6

  A highly enantioselective Mannich reaction of 3-substituted benzofuran-2(3H)-ones and isatin N-Boc ketimines catalyzed by a chiral biscinchona alkaloid catalyst was developed, which proved to be an efficient way for the synthesis of chiral 3,3'-disubstituted benzofuran-2-one derivatives. The nucleophilic addition products were generally obtained in high yields (up to 99%) with very good diastereoselectivities (up to >95:5 dr) and enantioselectivities (up to 98% ee).

  An enantioselective alkylation reaction of 3-substituted benzofuran-2(3H)-ones catalyzed by a chiral biscinchona alkaloid catalyst combined with TsOH center dot H2O was developed. The corresponding products, containing all carbon quaternary centers at the C3-positions of the benzofuran-2-ones, were obtained in moderate to good yields (up to 89%) with good enantioselectivities (up to 83% ee).
