  Enantioselective total syntheses of cyclopropane amino acids: Natural products and protein methanologs

  摘要：

  The syntheses of (-)-allo-coronamic acid, (-)-allo-norcoronamic acid, (-)-(Z)-2, 3-methanohomoserine, (-)-(Z)-2, 3-methanomethionine, and (2S, 3R)-Cbz-cyclo-Asp-OMe have been achieved in 45-68% overall yields from suitable intermediates derived from homochiral aminopentenoates which were obtained, in bun, from D-glyceraldehyde. The key synthetic step involves the quantitative and highly diastereoselective cyclopropanation of such precursors. The factors dealing with the control of stereoselectivity are highlighted and the main features in sidechain functionalization to the respective target molecules are discussed.

  Stereoselective Syntheses of (E)-α,β-Didehydroamino Acid and Peptide Containing Its Residue Utilizing Oxazolidinone Derivative

  摘要：

  甲基 N-Boc-N-苯氧羰基甘氨酸盐与各种醛反应，生成了相应的顺式-4,5-恶唑啉酮衍生物，这些衍生物通过碱处理有效地转化为（E）-α,β-二脱氢氨基酸。此外，恶唑啉酮衍生物的去N保护以及随后与Boc-氨基酸的偶联反应生成了相应的二肽，这些二肽被转化为含有高E选择性的α,β-二脱氢氨基酸的二肽。

  Reaction of methyl N-Boc-N-phenoxycarbonylglycinate with various aldehydes afforded the corresponding cis-4,5-oxazolidinone derivatives, which were effectively converted to (E)-α,β-didehydroamino acids by means of a base. Furthermore, N-deprotection of the oxazolidinone derivatives and subsequent coupling reaction with Boc-amino acid furnished the corresponding dipeptides, which were transformed to dipeptide containing α,β-didehydroamino acid with high E selectivity.
