  Stereocontrolled Synthesis of Highly Substituted Proline Esters via [3 + 2] Cycloaddition between N-Metalated Azomethine Ylides and Nitroalkenes. Origins of the Metal Effect on the Stereochemical Outcome

  摘要：

  The [3 + 2] cycloaddition reaction between several N-metalated azomethine ylides and nitroalkenes has been studied using AgOAc and LiClO4 as metalating reagents in the presence of triethylamine. The reaction is found to be very versatile and can be extended to homochiral nitroalkenes. In general, lithium and silver salts promote preferential formation of the endo and exo cycloadducts, respectively. The presence of a phenol moiety induces a shift toward the exo-cycloadduct even when lithium is used. A model based upon the experimental results obtained and SCF-MO calculations is proposed to explain the variable stereochemical outcome of these reactions.

  AgOAc/ThioClickFerrophos (TCF) complex catalyzed the 1,3-dipolar cycloaddition of azomethine ylides (glycine imino ester) to nitroalkenes. The corresponding endo-cycloadducts (88:12–98:2 endo/exo) were afforded in good yields with high enantioselectivities, up to 98% ee, without addition of external amine. AgOAc/TCF works as a bifunctional (Lewis acid and base) catalyst.

  Chiral complexes formed by phosphoramidites such as (S-a,R,R)-9 and Cu(OTf)(2) are excellent catalysts for the general 1,3-dipolar cycloaddition between azomethine ylides and nitroalkenes affording the corresponding tetrasubstituted proline esters mainly as exo-cycloadducts in high er at room temperature. The exo-cycloadducts can be obtained in enantiomerically pure form just after simple recrystallization. DFT calculations support the stereochemical results.

  The novel C-2-symmetric bis(imidazolidine)pyridine (PyBidine) ligand was easily synthesized in a single condensation of 2,6-pyridyl aldehyde and optically active (S,S)diphenylethylenediamine. In the C-2-symmetric PyBidine-Cu(OTf)(2) complex, imidazolidine rings act as "chiral fences" to shield the first and third quadrants. Use of the PyBidine-Cu(OTf)(2) complex as a catalyst enabled the highly endo-selective reaction of imino esters and nitroalkenes to give the adducts in up to 99% ee.
