  Green aldose isomerisation: 2-C-methyl-1,4-lactones from the reaction of Amadori ketoses with calcium hydroxide

  摘要：

  Saccharinic acids, branched 2-C-methyl-aldonic acids, may be accessed via a green procedure from aldoses by sequential conversion to an Amadori ketose and treatment with calcium hydroxide; D-galactose and D-glucose are converted to 2-C-methyl-D-lyxono-1,4-lactone (with a small amount of 2-C-methyl-D-xylono-1,4-lactone) and 2-C-methyl-D-ribono-1,4-lactone. Inversion of configuration at C-4 of the branched lactones allows access to 2-C-methyl-L-ribono-1,4-lactone and 2-C-methyl-L-lyxono-1,4-lactone, respectively. D-Xylose affords 2-C-methyl-D-threono-1,4-lactone and 2-C-methyl-D-erythrono-1,4-lactone, whereas L-arabinose, under similar conditions, gave the enantioiners 2-C-methyl-L-lactone-1,4-lactone and 2-C-methyl-L-erythrono-1,4-lactone.
