  Highly Enantio- and Regioselective Allylic Alkylations Catalyzed by Chiral [Bis(dihydrooxazole)]molybdenum Complexes

  摘要：

  A series of chiral C-2-symmetric bis[dihydrooxazoles] with a trans-1,2-diaminocyclohexane backbone was synthesized. In view of the promising results obtained by Trost et al with related bis[pyridine] ligands, we tested these new ligands in the enantioselective molybdenum-catalyzed allylic alkylation of 1- and 3-monosubstituted allylic substrates. Enantiomer excesses of up to 98% and branched/linear ratios of up to 11 : 1 were obtained with (E)-3-(alkyl)allyl carbonates. (E)-3-Phenoxyallyl acetate gave a branclied/linear ratio of > 20:1 and an ee of 98%. Crystal structures of the free ligand 7a and of its tricarbonylmolybdenum(0) complex 28 are reported.

  The catalytic asymmetric addition of β,γ-substituted allylboronates to aldehydes has been described. Promoted by 5 mol % chiral phosphoric acid, the reactions were broadly applicable, scalable, and efficient, allowing for the formation of 3,4-anti/syn-homoallylic alcohols bearing adjacent tertiary or quaternary stereogenic centers in a highly enantio- and diastereoselective manner (≤99% ee and dr >20:1)

  已经描述了 β,γ-取代的烯丙基硼酸酯对醛的催化不对称加成。在 5 mol% 手性磷酸的促进下，该反应具有广泛的适用性、可扩展性和高效性，允许以高度对映和非对映选择性的方式形成带有相邻叔或季立体中心的 3,4-反/同-高烯丙醇（≤99% ee 和 dr >20:1）。涉及手性磷酸的刚性椅子状过渡态有助于高度控制的反应。

  [GRAPHICS]A series of chiral C-2-symmetric bisoxazolines with trans-1,2-diaminocyclohexane backbones was synthesized. In View of the promising results obtained by Trost with analogous bispyridine ligands, we tested our new ligands in the enantioselective molybdenum-catalyzed allylic alkylation of 1- and 3-monosubstituted allylic substrates, Enantiomeric excesses of up to 98% and branched/linear ratios of up to 11:1 were obtained with (E)-3-(n-alkyl)allyl carbonates. (E)-3-Phenoxyallyl acetate gave a branched/linear ratio of >20:1 and an ee of 98%.
