An Optically Active D-Aldopentose Produced an Optically Inactive Aldaric Acid

question 72

Essay

An optically active D-aldopentose produced an optically inactive aldaric acid upon treatment with HNO₃. When this aldopentose was subjected to a Ruff degradation, a D-aldotetrose was generated. This aldotetrose gave an optically inactive alditol upon reduction with NaBH₄. Use these data to provide the structure of the starting D-aldopentose.
