  Catalytic Asymmetric Synthesis of Glutamate Analogues

  摘要：

  Utilizing our lateral metalation coupled with Jacobsen's catalytic asymmetric amino nitrile synthesis, we have demonstrated the ability to synthesize isoxazole-containing amino acid glutamate analogues in high yield and high enantiomeric excesses. Chiral centers alpha or beta at the C-5 position do not detract from diastereoselectivity of the Jacobsen-Strecker reaction.

  Lateral lithiation of ethyl 4-acetyl-5-methyl-3-isoxazolyl carboxylate with 5,5-dimethyl-1,3-dioxanyl as a directing group

  摘要：

  Lateral lithiation of ethyl 4-acetyl-5-methyl-3-isoxazolyl carboxylate, a functionalized isoxazole AMPA analog, occurs cleanly at the C-5 methyl group with 5,5-dimethyl-1,3-dioxanyl as a directing group. The 4-acetyl isoxazole derivatives were transformed selectively by a modified Willgerodt-Kindler reaction into the corresponding homologated methyl esters after deprotection.
