  名称：

  New isosteres of (R)-2-methylhomoserine and (R)-2-methylaspartic acid by alkylation of a chiral imine leading stereoselectively to a quaternary stereogenic center

  摘要：

  Imines obtained from either chiral 3-amino-4-silyloxymethylpyrrolidin-2-one 5a or 5b underwent alkylation to give, in good yield and total stereoselection, the corresponding 3,3,4-trisubstituted pyrrolidin-2-ones 8a-d where both the amino and the silyloxymethyl groups lie cis to each other, as shown by H-1 NMR spectroscopic data and NOE experiments. By removal of both the imino group and the chiral inducer from 8b, the pyrrolidin-2-one 12, an isostere of(R)-2-methylhomoserine 2 and the pyrrolidin-2-one 14, an isostere of (R)-2-methylaspartic acid 4 were obtained straightforwardly.
