Procedure

An alternative synthesis of D-arabinose consists in the oxidative degradation of gluconic acid, extensively described by Ruff in Berichte der Deutschen Chemischen Gesellschaft 32 (1899) 553-554. However, starting from glucose a minimum of three reaction steps are required to obtain arabinitol.
