  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.

  The first synthesis of a spirodiketopiperazine at the anomeric carbon of a pyranose sugar is described; an N-acylated bicyclic amino [2.2.2] lactone provides access to a new class of glycopeptide analogues of pyranoses and determines the anomeric configuration of the spirodiketopiperazine. The mannopyranose may be equilibrated to the more stable furanose form.
