  摘要：

  手性亲核催化剂 TADMAP [1, 3-(2,2,2-三苯基-1-乙酰氧基乙基)-4-(二甲氨基)吡啶]已由 3-锂硫-4-(二甲氨基)吡啶 (5) 和三苯乙醛 (3)，然后进行酰化和拆分。TADMAP 催化恶唑基、呋喃基和苯并呋喃基烯醇碳酸酯的羧基迁移，具有良好到极好的对映选择水平。恶唑反应特别有效，用于制备含有季不对称碳的手性内酰胺 (23) 和内酯 (30)。吲哚系列中 TADMAP 催化的羧基迁移相对较慢，并且具有不一致的对映选择性。建模研究 (B3LYP/6-31G*) 已用于定性关联催化剂构象、反应性和对映选择性。

  Regiodivergent Enantioselective γ-Additions of Oxazolones to 2,3-Butadienoates Catalyzed by Phosphines: Synthesis of α,α-Disubstituted α-Amino Acids and N,O-Acetal Derivatives

  摘要：

  Phosphine-catalyzed regiodivergent enantioselective C-2- and C-4-selective gamma-additions of oxazolones to 2,3-butadienoates have been developed. The C-4-selective gamma-addition of oxazolones occurred in a highly enantioselective manner when 2-aryl-4-alkyloxazol-5-(4H)-ones were employed as pronudeophiles. With the employment of 2-alkyl-4-aryloxazol-5-(4H)-ones as the donor, C-2-selective gamma-addition of oxazolones took place in a highly enantioselective manner. The C-4-selective adducts provided rapid access to optically enriched alpha,alpha-disubstituted alpha-amino acid derivatives, and the C-2-selective products led to facile synthesis of chiral N,O-acetals and gamma-lactols. Theoretical studies via DFT calculations suggested that the origin of the observed regioselectivity was due to the distortion energy that resulted from the interaction between the nudeophilic oxazolide and the electrophilic phosphonium intermediate.

  palladium(II)‐catalyzed enantioselective α‐alkylation of azlactones with nonconjugated alkenes is described. The reaction employs a chiral BINOL‐derived phosphoric acid as the source of stereoinduction, and a cleavable bidentate directing group appended to the alkene to control the regioselectivity and stabilize the nucleopalladated alkylpalladium(II) intermediate in the catalytic cycle. A wide range of

  描述了钯（II）催化的内酯与非共轭烯烃的对映选择性α-烷基化。该反应使用手性BINOL衍生的磷酸作为立体诱导的来源，并且在烯烃上附加了可裂解的双齿导向基团，以控制区域选择性并稳定催化循环中的核钯烷基钯（II）中间体。人们发现，在最佳反应条件下，各种各样的内酯都具有相容性，从而能够以高收率和高对映选择性提供带有α，α-二取代的α-氨基酸衍生物的产物。

  4-addition of azlactones to α,β-unsaturated trichloromethyl ketones catalyzed by cinchona alkaloid derived bifunctional thiourea catalysts was developed. A series of α,α-disubstituted α-amino acid derivatives bearing a quaternary stereocenter at the α-position were obtained in high yields with excellent diastereo- and enantioselectivities (up to -20:1 dr and 99% ee). In addition, the trichloromethyl moiety

  We developed a catalytic aerobic method to synthesize α,α-disubstituted α-amino acids through cross-dehydrogenative coupling of azlactones. Combining an iron catalyst with a bisoxazolidine ligand resulted in high catalytic performance, and cross-coupling with an indole proceeded smoothly under aerobic conditions. A wide variety of α-aryl and aliphatic amino acid derived azlactones were applied to the
