  Spirodiketopiperazines of mannofuranose: carbopeptoid α-amino acid esters at the anomeric position of mannofuranose

  摘要：

  Epimeric mannofuranose anomeric aminoesters are prepared from readily available azidolactones and can act as building blocks for the incorporation of mannofuranose units into peptide chains [carbopeptoids]; alternative acylating conditions allow either rapid acylation of the more stable but kinetically hindered amine or reaction with the less hindered but less stable amine to allow control of the anomeric configuration of the products. This is exemplified by coupling of the aminoesters with glycine derivatives to give dipeptide equivalents, and subsequent cyclization to spiro diketopiperazines, Anomers with the nitrogen function cis to the 2,3-diol are more stable than those with nitrogen trans; mannofuranose derivatives are more stable than the mannopyranose isomers.

  Anomeric spirohydantoins of mannofuranose: Approaches to novel anomeric amino acids by an oxidative ring contraction

  摘要：

  Bromine-induced oxidative ring contraction of an alpha-amino-delta-lactone gave a mixture of alpha-aminotetrahydrofurancarboxylic esters which may allow the preparation of stable amino acid derivatives at the anomeric position of mannofuranose. The synthesis of N-phenylhydantoins at the anomeric position of mannofuranose is reported.
