What is Studies on Ketoses, 8. Disaccharide Building Blocks from Isomaltulose: Glucosyl‐α‐(1→5)‐D‐arabinonic Acid and Ensuing Products about?

## Abstract A convenient one‐pot procedure, simply involving air oxidation in strongly alkaline solution, is detailed for the high‐yield conversion of bulk accessible D‐glucosyl‐α(1→6)‐D‐fructose (isomaltulose, 1) into the salt of the next lower aldonic acid, i.e. glucosyl‐α(1→5)‐D‐arabinonate (4). Being only two steps away from sucrose, 4 is capable of providing a variety of disaccharide building blocks with potential industrial application profiles: open‐chain esters, amides or alditols (8–12), or – via the respective 1,4‐lactone 5 and suitable elimination reactions – various enantiopure 2‐(5__H__)‐furanones (14–17) with a preparatively useful (5__S__)‐hydroxymethyl group, __O__‐protected with an acid‐labile glucosyl residue.
