6'-Linked ethers derived from D-allose, D-galactose, D-glucose, and D-mannose have been prepared in order to allow comparisons with the reported 6,6'-linked hexopyranose coyolosa, an hypoglycemic compound which has been isolated by extraction of the root of the palm Acrocomia mexicana. Comparison of NMR data from the ethers and their derived peracetates with corresponding reported data from coyolosa and its
