  Resolved Chiral 3,4-Diazaphospholanes and Their Application to Catalytic Asymmetric Allylic Alkylation

  摘要：

  One-pot condensation of PhPH2, phthaloyl chloride, and the azine of 2-carboxybenzaldehyde (1) results in the new phosphine, rac-N,N'-phthaloyl-2,3-(2-carboxyphenyl)-phenyl-3,4-diazaphospholane (rac-2), in 88% yield. Resolution via selective crystallization of the diastereomeric alpha-methylbenzylamine salts followed by coupling with amino acids and other amines provides rapid access to new collections of chiral phosphines (3). Pd-catalyzed alkylation of 1,3-dimethylallyl acetate and 1,3-diphenylallyl acetate at room temperature in the presence of 3 exhibits enantioselectivities as high as 92% ee and 97% ee, respectively, with strong sensitivity to the nature of the amino acid appendages. The presence of PF6- salts profoundly affects both the yield and the selectivity of catalytic allylic alkylation.

  A copper-based catalytic system, using an air-stable diazaphospholane as the ligand, was developed for an efficient Ullmann reaction between aryl iodides and alkyl or heterocyclic amines.

  为了使芳基碘化物与烷基或杂环胺发生有效的乌尔曼反应，开发了一种使用空气稳定的二氮杂膦烷作为配体的铜基催化体系。
