摘要：
An enantioselective [4 + 1] annulation/rearrangement cascade of stable sulfur ylides and nitroolefins has been developed through an efficient axial-to-central chirality transfer with the use of a chiral BINOL-derived sulfide as a reliable stereocontroller. It can provide pharmaceutically and synthetically important oxazolidinones in high stereoselectivities (up to 96:4 e.r. and >95:5 d.r.). Moreover, this strategy was also successfully applied to the asymmetric [4 + 1]/[3 + 2] cycloaddition cascade of sulfur ylides with alkene-tethered nitroolefins, and the corresponding enantioenriched fused heterocycles (up to 87:13 e.r. and >95:5 d.r.) were obtained in good to excellent yields (54-95% yields). © 2011 American Chemical Society.

摘要：
Chemical equations presented. An asymmetric nucleophilic addition/protonation reaction of 3-substituted oxindoles and ethyl 2-phthalimidoacrylate has been described. This strategy can give direct access to Cγ-tetrasubstituted α-amino acid derivatives bearing 1,3-nonadjacent stereocenters with up to 98% yield, 94:6 dr, and >99% ee. Dual activation is proposed in the transition state, and the opposite enantiomers can be obtained simply by changing cinchonidine-derived catalyst to the cinchonine analogue. © 2011 American Chemical Society.

摘要：
Over the last few decades, the catalytic asymmetric Friedel-Crafts alkylation has become a powerful strategy that provides enantioenriched structural motifs of established value in medicinal chemistry or complex target synthesis. While the traditionally chiral Lewis-acid catalyzed Friedel-Crafts alkylation has been extensively reviewed in the literature, we focused this review on the recent advances on organocatalytic Friedel-Crafts alkylations. According to activation modes, this review is divided into three main sections, including 1) alkylations via iminium catalysis, 2) alkylations via SOMO catalysis, and 3) alkylations by chiral hydrogen-bond donors.

摘要：
A highly efficient and enantioselective intramolecular crossed Rauhut-Currier (RC) reaction of nitroolefins with tethered enonates has been developed through cooperative nucleophilic activation and a hydrogen-bonding catalytic strategy (≤98% ee and 98% yield). The reaction features simple experimental procedures and is completely chemoselective and atom-economic in character. The potential synthetic applications have been demonstrated by the conversion of the RC reaction products into biologically and pharmaceutically valuable compounds with highly diastereoselectivity. In addition, computational investigations were employed to support the proposed mechanism and to obtain a good understanding of the origin of the stereoselectivity in RC reactions.
